Make a process which is running with root capabilities appear in a
standard ps output as though it belongs to user 'foo'. I can't change
ps; I can't change the kernel. I can only use the standard POSIX
APIs. I do have root on the system.

FWIW, I thought about it for a couple of days before tossing it to the
list, and I don't think it can be one. I'll be happy to be proven
wrong ;-)

Not yet, although it's on my "to investigate" list. It's a long shot,
most root kits I'm familiar with hide their processes completely,
rather than make them appear to belong to a different user.

Cheers,
