I've known people who did a MS in comp sci, followed by a 1 year MS program in financial math. The one guy I'm thinking of in particular was a pretty brilliant math/cs double undergrad who used the 1 year financial math program as a springboard into the NYC quant scene.

I've sadly lost touch with him, but there are a number of financial math grad programs out there. If you're really passionate about this technology, try one out and do some internships. Oh - and don't do it because you think you'll make millions.
