Is it possible to use ISO's with "boot"? I typed the following and I got "Must specify drive letter to mount image at.". I am using DOSBox 0.70.

This is what I typed:

1mount c c:\dos
2c:
3imgmount -t hdd 2 d:\[filename].img -size 512,63,16,142 -fs none
4imgmount -t iso 3 d:\diskimgs\[filename].iso -fs iso
5boot d:\[filename].img

Nope. Just floppy and HD images.

Would ISO support for "boot" be implemented in the future?

Not that it is very useful for games. It would be most useful to install other OSes but DOSBox does not support much in that department yet and probably won't for a while (although Win95 was showing some promise).
Booting from CDs is somewhat of a hack on real hardware. The process essentially piggybacks on booting from floppy. On many BIOSes all calls to floppy are redirected to emulated floppy image on CD after CD boot. I guess it can be implemented this way in DOSBox relatively easily if somebody is motivated enough to do that.

booting off isos would be nice, but support for CD-Roms (whetehr real or isos) would be a much nicer first step, when booting an image...

El-torito isn't enough, It will require emulation of IDE/ATAPI port to support more than just booting DOS floppy image from cd (as it uses mscdex based drive to access rest of the files on the disk).
