mtgox has an API.
If I had enough funds sitting on mtgox, I could trade instantly, although I dont have anything set up for finding unconfirmed transactions, or communicating with bitcoin clients. I have a shared hosting, so I can't put the bitcoin client on it.
The market moves fast and I suppose you could get burned by quoting someone a price, then the market moves. Someone could free roll you by offering to buy at a price, seeing if it goes up, then buying then, or something like that. Probably want to build in a decent exchange fee to ensure you dont get screwed.
It wasn't anything official, just a proof of concept. I'm more concerned about legal issues to pursue it any further right now, but the code is super easy and I'm sure anyone who cares could do the same thing really easily.
I just scan mtgox to see what asks and bids are available. I can figure out any of the following:
I have $X, how much bitcoins can I buy.
I want $X, how many bitcoins do I have to sell?
I have X BTC, how many dollars do I get?
I want X BTC, how many dollars do I need?
