I've never heard of any HPC computer using disk encryption. Though compute intensive work need not be I/O intensive, it might very well be. If there is a real need to keep your data secure in your HPC environment, other measures that encryption are just as effective.
Frankly, encrypting everything is just not the best solution. Especially since encryption doesn't prevent legitimate users of making copies on non-encrypted media and loosing those. I guess your IT staff just found a cool new toy, but well, I don't see any traces of procedures to help safeguard the data.
My word of advice: get a security-officer to define proper procedures for data classification and data handling, really, all you need is procedure and well then maybe, pgp whole disk will play part in implementing a proper data handling procedure for data classified as C=extremely high.
So because your neigbour is a terrorist, it is ok for the police to kill you, just because you happen to live next to a terrorist? Or even better, it is ok for a govenment to nuke your city because a terrorist lives in that city?
Now The militant blacklist are not even the police! They are civillians taking justice into their own hands, without first having tried to get the police involved in the problem they are trying to solve. "We'll just kill a bunch of random people, maybe nuke a city or two, maybe that draws attention to our case", this attitude is not less criminal than the terrorist acts you are trying to fight!
Now, as to how to fight the real problem, getting decent laws in place is the first step. This will probably never happen unless you make it very clear to the politicians you elect that this is important to you, as important as fighting any other crime. The second step is getting the police involved once the laws are in place. This will cost money, your (the taxpayers) money, but hey, you thought this was important, so you are probably willing to pay some extra tax.
...And his landlord knows he is a terrorist....
Which is more likely not true that it is likely that it is. Remember, you are only shooting nukes at a city, there is no police involved. The policy has no right to search a house without a judge having looked at the case. Where is the judge in your story? There is none! It is not up to the landlord to put people out of their house, that is up to the police to do on order from a judge, based on a fair trail. This is where blacklists go wrong, they don't obey the basic principles of justice....
This is obviously not possible with Open-Source, since permission to use the program is implicit; if the software exists you have permission to use it.
This is not true. It is still possible with open source software that the user has to pay for the right to use. Giving him the source-code with the software does not change that. What does change is the way users can submit change-requests or bug reports. Also the user gets the right to make changes to the source to make the program work the way he likes it.
Having the source Makes up for SOME lack of doc's, but I bet I can write a small procedure in C that nobody will ever be able to understand if it isn't documented.

Soon, we'll have:
X in the kernel
GNOME in the kernel
xterm in the kernel
a MUA in the kernel
and we wonder why Linux crashes 2 times a day....
