I have a special situation where it would be *extremely* good if users could open their own ports < 1024. SMTP and pop3, at the very least - FTP would be good too.

I was thinking, surely there would be a way to patch the kernel to allow this sort of activity.

Has anyone ever heard of such a thing?

Any idea where I could find information about this short of bugging lkml (which I really don't want to do)?

Why not allow users to run those services on higher ports? There is no rule that pop has to be on 110, for example. The users will just need to configure their client software to use another port.
