I'm not having luck using 'sendmany' from PHP. Did anyone manage to get it working?
The sendmany() doesn't look that hard:
It doesn't, does it? But I tried typing it in two or three different ways and got an error each time.
What tripped me up doing it in php was that I had to put (float) just before the send amount.
$bitcoin->sendfrom($account,$addr,(float)$amount);
Haven't tried sendmany yet.

All right, forget sendmany, I just sent out a bunch of separate transactions.

I bet on a boy and have received my prize. Thanks!
Cheers,
Received my 0.08 bitcoins. I had bet 0.05 on boy and girl...
Well, it was really unlikely you'd make money that way. You were basically not betting on the outcome, but rather meta-betting that the books would be lopsided by well more than 2:1. They weren't very lopsided, so you lost.

It's a boy!
Bitcoin’s gender distribution had to stay intact, after all. 
Congrats.
It's a boy!
Winnings will be distributed as soon as I can figure out how sendmany works.

D'oh. Is there a "don't send from this address" option somewhere in the client?
Counting up just the "received" totals since this thread started, it's now 1.29:1.25. So nearly even.

F+M twins ? 
Books are currently at 0.4 to 1.25...
And we're finding out around 18:30 (UTC)! I'll wait until midnight to post the answer, though.

^^ shhhh... don't anyone tell this guy about the block chain 
That's why unique addresses are a must
I'm the one that bet 1 btc on it being a girl... at this point by the current rules I stand to lose 0.038 btc even if it is a girl!
Let's hope others come to the party and even up the sides
Anyway, you'll be able to spend your profits on 0.0004 of a disposable nappy.

Well, it wasn't today, but it should be some time next week. We'll probably be told the date of our ultrasound appointment tomorrow.
doood is right: you can just use BlockExplorer to see the running totals. Here are all the boy bets and girl bets. (Note that I accidentally used a previously-used address for the boy bets, as the transaction record shows...)
As you can see, not much activity... at this rate, my cut is 0.13, and that's assuming the books balance themselves out before the end.
This hasn't gotten very much of a response at all, so I'll just point out that at the moment the books are unbalanced! There's a total of 0.1 riding on "boy" vs. 1.25 riding on "girl". Someone ought to come in and balance this out and make a positive expected profit in the process!

Well the payout should be close to double-or-nothing if there are enough bets. It's be easy to tell if the fix was in. Unfortunately not until after the event.
Not necessarily. If too many people bet on one side, I bet new betters would take the other. So you make your bets early enough that it evens out by people trying to get a "better" deal, then it doesn't look suspicious.
That's if he publishes running bet totals. If he doesn't, then the typical bettor would have no idea of which side is underbet.
