Joel, memory is certainly one limiting factor, but CPU is often the more 
important constraint on a SunRay. With a hundred users on a box if 
specifc apps start eating CPU, it doesn't take long to grind the box 
into the ground. Browser loading pages with poorly written javascript, 
java applet that's misbehaving, looping flash animation ... are just 
some of the things that can cause this to happen [check out bugzilla and 
look for memory issues to see how many are related to poorly designed 
pages].

The browser would appear to be the biggest hog on the system with regard 
to memory consumption. If the user has 20-30 tabs open with plenty of 
graphics on them, you can see heap usage for the browser going over 100 
Meg without any problem. Ideas have been knocked around to make the 
browser more efficient, from having it not store images in memory for 
hidden tabs, to improving how it allocates pixmaps on the xserver and/or 
having direct support in xorg for compressed pixmaps, but no one is 
currently working on implementing any of these ideas.
