so there is absolutely no way to use tm with a any kind of network share except for another leopard machine?
Correct. It's likely (but not guaranteed) that in the future Apple will also support storage connected to an Apple Airport wireless base station.
Yes, I use a Ximeta enclosure, now $40 at Frys. Got mine I think for about $15 after rebate. Use a Maxtor 500 GB drive ($90 at Frys). Downloaded the Leopard driver from their website. Seems to work fine. I have it connected to one of the switch ports on my wifi router (dlink dir655) My daughter also has one at college in her dorm room.Would something like this work? Apparently it shows up as a local disk and not a network share. Do any other NAS drives/enclosures work?
