256MB should indeed be enough, (max mem used at this moment for me was
about 6% of 1GB: 60MB)

It doesn' matter if you have 1gb or 2gb memory. You should enable remote
syslog if you are concerned storing them...

A fast processor and good NICS help a lot.

The whole stability of a system lies in the stability of the hardware
(good hardware, good cooling...) Some people seem to forget this (with
possible lockups as end result)

1) there very expensive, for that moment you can buy a good hardware
base platform
2) don't know about Nomadix but IIRC cisco is mostly C++ programmation.
3) maybe more options? (or less ;) ) Enough people are working on
getting the same features or even more and better ones into m0n0wall :)

In the end only one thing is important: does it work like you want it to
work or not?

M0n0wall can do exactly the same (and already even more) As long as
backend system is RADIUS it doesn't matter if you're using Active
Directory-IAS, freeradius or Funk software...

It depends on the radius server you're using...

I'm testing everything against Freeradius but it sureley works on MS-IAS
