Hmmm.  I don't really know about this one.  What kind of processor does 
it have?

Check out the user survey located at:  http://www.macbsd.com/~spearce/ to 
see if anyone is in fact running it on one.

Yes there is!  Check out the FAQ for more on this one (it's at:
http://www.macbsd.com/macbsd/macbsd-docs/faq/)

I don't know about this one either.

Sup is a method for retrieving source files.  Basically, instead of 
downloading the entire source tree everytime it's updated, you only 
download the changed files.

Later.
