Given the biggest "trade secret" on OkCupid is the matching algorithm and its laid out so that anyone who wanted to would be able to implement it, I bet he would be pretty excited to hear that 300M people in China found his idea awesome.

Also it would probably be faster to write a copy from scratch in rails than figure out the various dependencies for OKWS and SFSLite (unless that's really improved since I was there). :)
