Lower fees when you're sending to several addresses.

Good question.  Since the sendmany is just a single transaction, even though it may involve many addresses, it will be denied if just one of those addresses is invalid (i.e. checksum doesn't match).  It will also deny the entire transaction if the client wallet doesn't have enough funds to cover the entire transaction.

If you're playing with the RPC interface, I recommend you set up a client pointing at testnet to play with. That way, you can experiment with invalid stuff all you want and not worry about losing real coins.

The 0.5 client seems to be able to send BTC to more than one address with one transaction (via the UI). Does anyone know if that uses 'sendmany'?

Oooh, neato.  It must use sendmany - that's the only way I've ever heard of to send to multiple addresses in the same transaction.

I haven't actually tried it, but on the "send" tab, you can add multiple recipients with different amounts of BTC.

my story:

I need to fund 'a lot' of addresses to print 'offline' bitcoins
in the past I had to send bitcoins to them 1 payment at time

Now all I need to do is to run (offline) the script from bitaddress.org, parse it for address & private key and even get QR codes.
To fund each address, all I need is to add them to a single transaction.

My test tx showed up as a single tx to many addresses. Great improvement IMO.
