coan.net: I don't know if such an abbundance would be good. Take a look at the poker tables - you can go in and out when you feel like it, but there's usually only 1 or 2 tables with players at most...
Now, think about people signing in for a game that starts in 10 minutes, keep playing the rest of their games, and when they go in to play in the pond, find out that either they have just timed out, or go in advance and wait 3 minutes staring at a page, waiting for the pond to start...
Doesn't seem like it will be very popular to me...

Suggestion to add onto this, if they are implemented this way - If I'm in a live Pond, have something popup on me when the time comes for me to make a bet no matter what page I'm at (as long as it's a page in BK, of course ).
