Whoops, should've read this message before posting...I didn't realize
you were proposing use of Mozilla directly.  When I criticized mozilla
I was referring to their writing a bunch of custom widgets, on top of
GTK; they kept all of GTK's bloat, added custom skinning on top, ignored
GTK's theme support, and introduced a lot of bugs to boot.  They could
have used XUL regardless of this, and still kept the default widget
implementations provided by GTK.

XUL is too low-level IMO.  It can't be used to describe a UI in a 
way that will render just as well on a PC or a PalmPilot.  But
it's a good point that it must be possible to have some client-
side code, so that not every interaction requires a round-trip to
the server.  Maybe Javascript is a good choice.  (And again, if 
a Scheme-like language were used, then both appearance and behavior
could be described using the same language.)

These are part of Mozilla, why would you need to replace them?
EROS would just be generating XUL, right?  And you'd run Mozilla
somewhere else.

Again if you don't couple them too tightly, then who cares; surely
the license of the system used to generate the XUL is irrelevant?
