Not sure which Ant you've got, but on the S3, edit the file /etc/init.d/cgminer and add this to the PARAMS line (line 70):
--btc-address YOURADDRESS
and restart the mining process.
Another option is to setup your own pool on a server in your network... you can use ck.'s ckpool if you're on Linux... or you could configure an NOMP/MPOS/CoiniumServ/whatever pool and mine to it just like you would any other.
Or, you could save yourself the hassle and just point your miners to solo.ckpool.org
