I'm currently running an NFS fileserver with 384M RAM, which seems to
work with some restrictions, but it is also putting pressure on the CPU,
which is a 700MHz PIII and this is not only while accessing compressed
You might be able to get it running on a 256MB 4801, but don't expect
any speed wonders.
The upcoming 5501 might be a good candidate if populated with much RAM.
If I got the prototype picture on soekris.com right they have 512MBit
chips soldered, which gives 256MB only - more than enough for most
embedded use, but not with ZFS as it stands right now...
That said - I don't know what the default population really will be.
