EDIT: Self-solved, it was IBM (Japan's) "WebBoy"

First English mentions with info that come up nowadays:

Old page still around mentioning demo version/etc: http://www.basterfield.com/pc110/links.htm

So LGR's recent youtube video about the 'Commodore' Web.it (which I lusted after soon after I learned about it a year after release) reminded me of something else I desperately tried to find a copy of around 1998/1999...

At that time I was still 100% DOS, using Arachne for web-browsing, and I found out about the thing I'm trying to identify:

It was a DOS-based web browser (and I'm pretty sure email+more suite), and there originally was a early demo version out which I used, with promises of it coming out soon as a full commercial product, but then the name changed and it became some business-use-only package.

- I'm 99.99% sure it was tied to either IBM or Intel.
- It wasn't Caldera/DR WebSpyder...it wasn't a spinoff of Arachne or anything else around.
- I'm not thinking of some other DOS-based suite like NetTamer/Minuet

It's really bugging me because I know it had a simple name, and it's on the tip of my tongue because it was one of my holy grails to find for a short time 🙁
