        I'm running Xinside's Xserver on one of my systems, and it's
just about as large. The mention of those old Sun workstations brings
up another point, though. On Unix workstations I'm used to seeing 
8 bit color (or less, as in the case of the mono X stations above).
On PCs, most everything's 24bits these days. That means that some
things will be four times as big (X generally uses 32bit words 
rather than 3 bytes to describe a color value in a 24bit server). I
was rather shocked the first time I saw how large a PC-based X server
on a host with 24bit color could get. So if you're used to seeing
X running on Suns and HPs, it's quite a jump in size.
