OK. Given that there is only a ISA bus in the unit there is not much point installing a NIC over USB as it would only be 10Mbs. Pity the Motheboard doesn't have one built in :(
DHCP - not a good idea if you plan to connect it to an existing network which may already have one (like me). It would probably be better just to hard code a reserved IP address into it (192.168 or 10.).
I love the wireless idea!
Paul, you hit the nail on the head. I wanted to know if I could FTP all my Mp3's into the unit then ask it to rebuild the database using the id3 tags. This is then used to do searches by artist, album, track name, track number, etc ...
