I believe that anyone can take the GPLed code, add their mods, and then
resell it *provided that they provide the source code to it*. Kinda like
RedHat does with its linux distro.
Not that you insinuated that this is the case, but it should be pointed
out that the FAQ point for Jabber licensing:
makes it clear that 'jabber' is a protocol standard, like http, and you
can make a proprietary client all you want, like the IE browser.
There's another question in Saradhi's post and that is "GPLing" the look
and feel of a client. There's really only so many ways to make a client
look (WinJab looks like Exodus looks like Yahoo IM, etc). So with
bchat's "Business Chat" IM looking like ColinJab that doesn't
automatically mean that they copied it. Maybe they copied the look of
it, who knows. It would be interesting to see if an author of a GPLed
work can force someone to reveal their source code (didn't this happen
with a DVD player recently?)
