>>But, how does one mange the source?

iTunes.

>>Does iTunes have to be running on a Mac continuously?

Yes.

>>If it's remotely located, how can one change the song?

How remote??

>>Does it require a wireless router?

Anything that supports wireless repeaters (WDS) should work. I believe the ever-popular buffalo wouters would work.

>>just the AirPort Express device?

just the device

>>Is AirTunes 'alive'?

Yes, but it hasn't been upgraded because its "just worked" from day one.
