Well, I have access to 11 CPUS under linux and 40 under Windows desktops
which are nearly 100% idle. So it is clear that I may gain a lot of CPU
time running NAMD on those.

This is an interesting option, but it has some issues:
- These are desktops, and it would be hard for me to run arround inserting
the CDs rebooting etc. I might do it through PXE, bu still, it is a
- I could use them only during WE/nights
- NAMD (unlike PVM) does not manage disconnecting/reconnecting hosts, so
the simulation will crash whenever a client stops (correct me if I am wrong)
