Interesting. I just installed Webot and have the following observations to share:

1. Interface is user-friendly. Very intuitive and it found BOTH my computers once I logged in. Flash interface took awhile to load over WiFi, so I dread to think how long this might take over 3G/HSDPA

2. The buffering takes so long that I wonder if it is buffering/streaming or if it is downloading the track and then playing it off a cache somewhere.

3. For some reason, I could not get it to play Nelly Furtado's All Good Things (Come To An End), but it kept skipping two tracks down to Alice Cooper's Poison instead. Needs more tinkering about to find out what is causing this strange behaviour.

4. A song takes approximately 4 to 5 minutes to 'buffer', and I wonder if it will automatically 'buffer' the next song while the current one is playing, or if it will just do it between tracks (which means another 4 to 5 minutes before the next song starts)

5. Search works well

Not bad for a beta, though
