If that's easier than hand-coding GTK+ (or Qt, or Aqua, or Win32) code,  
that *alone* might make it worth doing....
Note, though, that menus would, at least in part, be per-platform; for  
example, "Preferences" would be under the "Ethereal" menu in Mac OS X,  
but under some other menu on other platforms.  Multiple XUL files, in  
cases where there's a real UI difference due to different  
conventions/rules on different platforms, probably wouldn't be too bad  
(and if you can do the equivalent of #includes in XUL files - does  
SGML/XML support that? - there might be even more common code  
available).
Can this handle "custom" widgets - or subclassing existing widgets?  We  
might want to do that for the packet list, to implement, for example, a  
list where the text in the columns is supplied by callbacks and not  
even generated for packets that aren't visible.
Does this seem like a viable approach?
It does to me.
(Longhorn will have an XML-based language for GUIs:

dnfoghorn/html/foghorn10272003.asp
and Mac OS X Interface Builder nib files are XML (I think there might  
also be a non-XML NeXTStEP format as well); it appears that Glade also  
uses XML, and Qt Designer uses - wait for it - XML to describe UI  
stuff.  So who had that idea first?  Mozilla?  Or did somebody do it  
before them?)
