Not really. Any 100Mbps switched network shouldn't have a problem 
keeping up.

Probably a non-issue, but you can always buy more RAM. My frontend box 
rarely if ever touches swap.

I did a diskless epia at one point in the past. Worked fine for the most 
part (for SDTV-only, of course). I found it more hassle than it was 
worth though, especially since I had a spare laptop hard drive sitting 
around, which makes for just about as quiet a system, and easier to 
update (now, if you had multiple diskless frontends, a single shared nfs 
image would start to be less hassle to keep in sync than upgrading 
multiple hard drive installs).
