Hi,
Hope this isn't too late.

This has pretty much been answered by someone else so I'll leave that.

As noted, FreeBSD was originally designed for x86 machines. There is now
an alpha port and a MIPS port is being worked on. Not sure if the
development is continuing on the Sparc port.

All of these are available.

not sure - I used to know this...

- FreeBSD is a complete system, Linux is just the kernel; each
distribution has added its own userland stuff
- FreeBSD has the ports system for easy installation of software; I find
this easier to use than RPMs from Red Hat. I've never used the Debian
package system but have heard it's nice. There are at present 2100 ports
available and more are being added constantly.
- FreeBSD uses CVS to maintain the source code. A user can then use CVSup
to easily update all the source to track the latest developments rather
than applying patches by hand.
- FreeBSD is descended from the original Berkeley Unix; Linux is descended
from Minix and is more of a clone of Unix.
There's certainly lots more.

NIS and DNS certainly - not sure about others.

Yikes - that's too small. I seem to recall 2 GB but that may be too
small.
> Is clustering supported on FreeBSD?
I seem to recall it is but ... can't give any quick pointers right now.

PicoBSD runs on a single floppy. A minimal install of FreeBSD will take
about 60 MB (wo/ source, X, or any applications).

This has been answered.

see above for a few
