Isn't it what the "new" Google Groups does?


(and FYI GMail does it the other way around: the "find people" dialog
box in Buzz is made with GWT, AFAICT)


Any performance implications ???


Unless you compile your Closure "lib" (with the Closure compiler) once
for each "permutation" of your GWT app, and load the appropriate one
(corresponding to the same browser as the current GWT permutation),
then the Closure code would use feature/UA detection at runtime
(e.g. "is this IE?" would still be performed whilst GWT already
determined it's running in Firefox, but it didn't tell the Closure
code...)
And of course, if you don't compile the Closure code (with the Closure
compiler) at all, it'd be even worse as each goog.require() would load
an entire new script (i.e. make another HTTP request)
