Also; Checking the balances of different accounts on the blockchain:

web3.eth.getBalance(web3.eth.accounts[0]);

web3.eth.getBalance(web3.eth.accounts[1]);

Try to set up a Watcher to react whenever anyone sends a coin using your contract. Here's how you do it:

var event = token.CoinTransfer({}, '', function(error, result){
if (!error)
console.log("Coin transfer: " + result.args.amount + " tokens were sent. Balances now are as following: \n Sender:\t" + result.args.sender + " \t" + token.coinBalanceOf.call(result.args.sender) + " tokens \n Receiver:\t" + result.args.receiver + " \t" + token.coinBalanceOf.call(result.args.receiver) + " tokens" )
});

If you want to detect received amount of ether use msg.value as usual. Just don't forget to include the payable modifier.

To know how many tokens has your contract access to, you can execute from you contract tokenContract.allowance(msg.sender, this)
