The relevant snippet from my conversation with DH:
DH: This is also true. We just have to make sure that you're ready to play
nice with the other users on the machine, that's all!
DH: Not that I have heard of, but it is known to be just a bit CPU intensive.
You're going to want to start this application on a DreamHost PS, as I
don't see it playing too well with the other users on a shared system.
Please let me know if you need anything else!
