I was testing Qt4 on an Intel graphics system and it still seemed
sluggish. :-)  Another area of concern is with remote desktops (e.g. thin
clients); how will rendering be handled in that case?  Will we need to
have Chromium (the GL renderer and stream processor, not the browser)
developed and installed to make things work?

Sounds good to me!  I'll wait for Qt5 then before giving it Qt another
serious performance test.
