If anyone can show me a combination of hardware that could fit into the empeg (redesigned or not) that could actually utilize GigE to capacity (as well as show any kind of reasonable NEED for it) I'll PayPal you $5.
7200rpm 2.5in drive with head rate over 500Mbits/s. Two of, that's GigE saturated. (But not by much -- it's probably not worth stretching to 10GigE.)

I'm sorry if I'm being an ass, but it's getting a bit sad. If you could (somehow) cram drives capable of a sustained 80MB / second into the empeg, you still would only be utilizing about 640 megabit.
Right -- that's much faster than the next slower Ethernet, 100Mbit. Similarly, you'd want Firewire800, not 400.

Not to mention, do you really need to be able to change out all the music on a twin 80gb empeg in 32 minutes?
Are you claiming that 32 minutes is not a perceptible delay? If I tell my PC to do something and it takes 32 minutes, I'd hope for it to be made faster.
