UPDATE
Generated blocks are now propagated over the network. Bootstrapping and main branch switching are the only unimplemented features left.
I got some offers, on the launch or shortly after it we will have the following services:
1] Faucet. It will be funded by our donations
2] Currency exchange. Classical BTC-to-NXT-n-back exchange
3] Stock exchange. If I got it correctly this is going to be a simplified (for non-pro traders) version of a stock exchange, can be used for crowdfunding
4] Virtual goods store. The goods will be provided by ordinary users (books, links, game codes, anything represented as plain text)
