Forgive me if this is a FAQ

I want to use FreeBSD as a dial-up PPP server, with 4-8 modems hanging
off the back end.  Most (all?) of the users would be using Windows 95 or
NT, but there may be a few others.

What I need to know is:
1. What multiport serial board will incur the least overhead?  Do they all
   incur about the same interrupt overhead or is there some "smartness"
   that the kernel can take advantage of with some?  There's also the
   question of reliability.
2. Is there a real difference between user-mode ppp (iijppp?) and
   kernel-mode WRT performance?  I would think it would, especially as you
   add more serial ports.
3. What kind of machine will do the job?  I'd think a 486/66 will handle a
   few ports simultaneously, but where's the cutoff point?  Maybe the
   answers to questions 1&2 affect this one.

There must be lots of people out there who use FreeBSD for this purpose.
Maybe someone can relate their experiences with some particular hardware.
