6) Send bitcoins to the multisig address.

7) Time passes.  Now, at least two parties are happy, and want
   to spend the bitcoins.

* Start from last processed block hash
* Call getblock
* Iterate through all transaction ids (which really are *all* txids, and not just those in your wallet - this is the first part of the key to the process)
{
   * call getrawtransaction on each txid (which also lets you inspect non-wallet transactions, 2nd part of the key to the process)
   * Iterate through all vouts
   {
      * check each address in the scriptPubKey list to see if it matches your multi-sig address
      * if it does, you've found a deposit! You can determine the number of confirmations from the call you made to getrawtransaction 
   }
}
* Goto next block hash
