| // un"addresses" contract object | |

| myContrac2.address = '0x12345678...'; // add address later | |
| // initiate with address | |

| // contract object events and methods | |
| myContrac.call({from: '0x1234...'}).myMethod(param1 , cb) // calls cb with result | |
| myContrac.transact({from: '0x1234...'}).myMethod(param1, cb) // calls cb with tx hash, in the future we could return a event transmitter | |
| myContrac.getData.myMethod(param1) // get only the data of the call '0x23456787654323456765432340000000000000000000000034' |
The new keyword is necessary when creating a new instance, to make it clear that it is a new instance, imo:
var contract = new web3.eth.contract(abi, address);
Ah, not sure what I was thinking. new looks good. 👍

intersting idea, but the main problem is namespace problems, which i try to avoid. What if you name your contract event "mined"? then it would clash..
