Yikes.  That'll work, but I'd be uncomfortable with that solution.  I 
definitely prefer (b).  Too many moving pieces to go wrong.

I just replaced the main server in my house (a 10 year old machine with 
Gentoo on it) with a Sheevaplug.  Took me one all-nighter to set it up 
and move everything over.  It's been working great for almost two weeks 
now.  Pulls 5W not including the external HD.  The best part is how much 
longer it'll stay up on the UPS when the power fails.

The next project is to wire in a serial GPS with PPS.  Then, it'll be my 
stratum1 time server as well.  :-)

For $99US a pop, you could get three Sheevaplugs and have separate 
servers.

Jason.
