Listener count is not a good indication I don't think.  I think that
it's possible to figure out this information from the other information
provided.  Ie, what's in the description tag?  Also, this is
time-dependent data.

Video still has a bitrate, and that is a better judge of quality.
Certainly with current technology, I'd rather eat the framerate at lower
bitrates, than watch a bunch of blurs.

We could add a second tag 'rate', which could be in kHz for audio, and
in fps for video based streams.  We could also add a 'channels' to
describe the number of audio channels (it's not unlikely we will see
surround sound Ogg streams) and maybe a 'size' for picture size (ex.:

I think so.  I want people who like my station to be able to contact me.
Certainly some fields are mandatory, but I think people who listed their
email (or a contact email in general, even if it's
stationmaster at mystream.com) probably care more about their station.  I
have emailed plenty of broadcasters in the past who were doing
interesting things.  And it was always a pain in the ass to fidn their
address, especially if they didn't list it on their homepages.

It's time-dependent data.  If a client wants that, it shoudl request it
from the server to make sure it gets a valid answer.  It does us little
good to display what people played 10 minutes ago and say that's what
they are playing now.
