From the Ethereum Builders:
"To make your Ðapp work with on Ethereum, you can use the web3 object provided by the web3.js library. Under the hood it communicates to a local node through RPC calls. web3.js works with AlethZero, geth and Mist, and also in an external browser if one of the former nodes are running locally.
web3 contains the eth object - web3.eth (for specifically Ethereum blockchain interactions) and the shh object - web3.shh (for Whisper interaction). Over time we'll introduce other objects for each of the other web3 protocols."
