X. G. makes two products: a laptop and a desktop X server. The laptop
version does not support overlays (as I just found out on their web
site). The desktop version does, on most hardware it supports which can
do them. I tried the demo version with some success (though a wierd
hangup or two), on my Permedia II based video system.

Good Luck,

JD
