The one responsible for rendering on your local screen certainly does. 
How the connection from the remote application to it works, remains to 
be designed. E.g. the app server on the remote machine could act as a 
proxy.

I'm not sure, what kind of memory usage you're thinking of here. 
Supposedly physical memory. But whether the drawing code for bitmaps 
resides in libbe or the app server executable has no impact on physical 
memory. The libbe code resides in shared memory.

Only that rendering bitmaps in the application wouldn't stand in the 
way of running applications remotely, since one can simply do the 
drawing in the app server in this case (though I think, that wouldn't 
even be necessary).
