If you are not swapping, you probably don't need to worry about it.
There are two of us logged into my LTSP server at the moment (both of
us memory hogs ;-) and I'm seeing almost a gig of ram being used. But
if you take a closer look, you'll note that ~500M of that is buffers &
cache:

[eharrison at ltsp eharrison]$ free
             total       used       free     shared    buffers     cached
Mem:       2074724     994368    1080356          0     323320     195120
-/+ buffers/cache:     475928    1598796
Swap:      2039800          0    2039800


Rather than having unused ram go to waste, Linux makes a huge cache out
of it. If you need the ram for applications, it just automatically makes
the cache smaller.
