[phenixbb] off topic - linux flavors for crystallography

At the risk of hijacking the thread, is the other type of "safety" 
considered? Our university is cutting net access to unencrypted 
computers, after now-publicized hacks originating from a foreign 
country. They do not seem to understand or know solutions for encrypting 
linux machines (they are also banishing XP; all FPLCs may have to come 

So, to cut to the chase, does anyone run RHEL/CentOS/Scientific Linux on 
encrypted disks? I am assuming dm-crypt with LUKS would be the way to 
go, and I would appreciate to hear about how easy it is to set it up and 
maintain. Can this be done without wiping clean the system? We are not 
system admins, and don't want to be. Otherwise, we may be forced to 
switch entirely to Macs (a Mac OS X Server as our SBGrid server?).
