Forwarding / proxy contract to register names

[chriseth]

A specific contract should forward new requests to register names to the actual registrar. It should work by just sending a transaction with the name as data, i.e. its fallback function should forward the request to the registrar. Furthermore, there should be at most one successful register attempt per sender.

contract RegistrarProxy {
    mapping (address => address) addresses;
    address registrar;
    bytes32 functioncall = sha3("register(bytes32,address)");

    function RegistrarProxy (address _registrar) {
        registrar = _registrar;
    }

    function () {
        if (addresses[msg.sender] == 1) {
            throw;
        }
        if (registrar.call(functioncall, msg.data, msg.sender)) {
            addresses[msg.sender] = 1;
        }
    }
}

Can you move it to GitHub to be loaded into remix?

I think the proxy represent an event so it should have a name. And that name should go to the registrar.

Also, should we allow the user to add additional message? Line name?

the name to register is msg.data

Shouldn't we have a function making suicide ? we'll call it when disabling proxy
