When does OpenCoin Inc intend to make the Ripple server code public? Is there a definite timeline or not? Thank you.
We have publicly stated that we don't expect the code to be made publicly available in less than two months and that we would consider it a failure if we didn't make the code publicly available before the end of the year.

Right now, we've received a lot of public feedback and are trying to make changes responsive to that feedback. See this github issue for an example. It will be very hard to make significant changes after the source code is public.
