Multisig wallet, very useless

multisig.js

contract multisig{
    struct tx{
        address to;
        uint amount;
        mapping (address => bool) approved;
    }
    uint nextId=0;
    mapping (uint => tx) txBook;
    address[] owners;
    function multisig(address[] _owners){
        owners=_owners;
    }
    function make(address to, uint amount) constant returns (uint id){
        txBook[nextId++]=tx(to,amount);
        return nextId-1;
    }
    function verifySend(uint id){
        txBook[id].approved[msg.sender]=true;
        bool verified=true;
        for (uint i=0; i<owners.length; i++)
            verified=verified&&txBook[id].approved[owners[i]];
        if (verified)
            txBook[id].to.send(txBook[id].amount);
    }
}
