Actually, I use a static IP on my PC, my modem is all that can use DHCP. However, I don't really see how you can draw the line between a dumb terminal that basically does nothing and an auto negotiation for IP, DNS, and gateway information. It's not really a matter of the remote system doing the processing for your system so much as the remote system keeping the database (albiet a rather small one usually) of information on which IPs are currently marked as available, perhaps which MAC address will have a particular IP reserved, etc.
The fact is, there's a reason that those things are not already more popular. Did you know that if you use the display hook mirror driver, you get pretty surprising speed out of those remote desktop things? The driver still isn't so super fast you're going to be playing any 3D games on there, but, nothing's stopping you from remoting up to a server on your lan and playing minesweeper through that. Why don't you? And don't answer because you're bored with minesweeper, even if you enjoyed it, would you really go to the lengths of using the remote server if your system right there can do it? Do you really want to rely on something that will have service outages and such, possibly right in the middle of a game or maybe even an absolutely vital application? I for one would pay, oh, say roughly the amount I spend on hardware, perhaps, oh, I don't know, say the stuff in my signature rather than a subscription fee to avoid this problem.
The fact is, your system can process the DHCP information more quickly than many routers probably if it's keeping the information in it's own memory much like the router does. But, DHCP is an innately server thing in that you need a central system tracking the information lest you increase the amount of work actually needed to track it. However, something such as minesweeper, a single player game really is just stupid to waste the server's cycles on when you have a perfectly good copy already. What's more, maybe this is some future and you have a 3d accelerated mine sweeper using all sorts of pretty graphics and, heck, a 3d playing field while we're at it (and I'd like to see Java do that worth a crap, because I haven't seen it do anything decent yet.) Step up to the REAL games where having it on your own system means you can do things such as upgrade your video card to get better quality, or play offline on your laptop when the power is off and the internet connections in the area are down. Now imagine switching to the dumb terminal -- oops, the power just went out, and battery backup is useless because you can't get to the server. Well, you wait five hours, give up, go to sleep, get up the next day and try again to find it's finally all back up, yay. Now you get on and find that the servers are bogged down with players and can't handle playing your simple minesweeper game at a decent framerate today (but, don't worry, they promise faster speeds in the future as they upgrade their servers.) If only those two people playing Doom 6 would just stop hogging half the cpu cycles for five minutes... Luckily nice safe Half-Life 5 elected to majorly degrade all the AIs and all visual/audio qualities so that they don't stress the servers as much, so you can maybe play that later when those jerks playing Doom 3 get offline already.
Kind of see where I'm going with this? Dumb terminals have their advantages, specifically in the business world, and that's where they have potential to work and are even actually used occasionally today. In the home user world, they very much do not belong, and this is why they have never caught on.
Anyway, all I can say is you've given me new respect for the fact that I DON'T have to pay a constant subscription fee to write reports in Word or to play Far Cry or just whatever the heck I feel like doing, be it stare at the screen. And, I promise you one thing, I'm NOT paying to post this on these forums...
EDIT: BTW, if the next thing after Vista lacks NTVDM, then something along the lines of DOSBox WILL be integrated, if not by MS, then by a fan who's sick to death of it being impossible to run anything from those days on that system without having to reboot back and forth and close down everything running in the background. Let's just call the project VDMSound^2, shall we?
MS may not care, but, that doesn't mean no one does. I just can't help but think that it could be useful from a software standpoint to take direct advantage of software such as this and stop using things like the NTVDM in favor of the more accurate emulated system to the extent that is needed.
