@s{quotedtext} @s{quotedtext} You can talk to the running bitcoind either by:
 1. sending JSON-RPC calls; see http://www.bitcoin.org/wiki/doku.php?id=api for more details.
 2. re-running bitcoind and giving it extra arguments; it will figure out that there's already a bitcoind running and will pass along the commands.

For example, running "bitcoind help" gives you the list of commands it understands:
Code:
bitcoind help
getaddressesbylabel <label>
listreceivedbyaddress [minconf=1] [includeempty=false]
getreceivedbyaddress <bitcoinaddress> [minconf=1]
getbalance
getblockcount
getblocknumber
getconnectioncount
getdifficulty
getgenerate
getinfo
getlabel <bitcoinaddress>
getnewaddress [label]
getreceivedbyaddress <bitcoinaddress> [minconf=1]
getreceivedbylabel <label> [minconf=1]
help
listreceivedbyaddress [minconf=1] [includeempty=false]
listreceivedbylabel [minconf=1] [includeempty=false]
listtransactions [count=10] [includegenerated=false]
sendtoaddress <bitcoinaddress> <amount> [comment] [comment-to]
setgenerate <generate> [genproclimit]
setlabel <bitcoinaddress> <label>
stop

To figure out what your bitcoin address is, run:
bitcoind getaddressesbylabel ""
(your default address has the empty string as its label).
Code:
bitcoind getaddressesbylabel "Your Address"
To figure out how many coins you have, run:
Code:
bitcoind getbalance
or
Code:
bitcoind getinfo

Regarding running headless:  the non-daemon bitcoin will run via remote (e.g. ssh forwarded) X-windows, if you install the necessary X11-client stuff on your server.
