Currently programs that do that have to rely on themselves to do it
right, that is, bind to the port and drop root privileges.
I think capabilities are really being forgotten. I can only remember
of one program that uses them for security purposes, xntp, and from
a specific distro. It only has the CAP_SYS_TIME capability or something
like that so that it only has privileges to change the system clock.
I'll use it now, of course, for CL7.0.

I don't, I'm sorry.

Sure. But I would rather prefer to have more programs using capabilities,
even if only to find bugs in the capability feature... :)

libcap is already in the distro, let's start linking stuff to it! :)
