I use the MiniMyth distro (www.linpvr.org) on an EPIA SP13000 as my
FE. It runs diskless, boots via PXE, and has enough RAM not to need
swap (1GB). There's a configuration option to run the root fs over
NFS, but I preferred to add RAM.

Performance over wired ethernet is just fine - although I don't do HD.
My SD streaming tops out at under 10Mbit/s, so there's no problem with
100Mbit/s ethernet any more than there would be with a standard
disk-based FE.

If you're already up to speed with PXE, tftp, syslinux etc then you're
pretty much good to go - MiniMyth has all the hard work done for you.
Of course the great thing about diskless is that it's so easy to try
