Jgarzik's been doing a lot of good with his patches. I for one have incorporated his GetBlock and ListTransactions patches into my unofficial builds.

That said, I guess we do need to clarify the legal status of everything he's made now. Jgarzik, could you please publish a license or at least go on record with your feelings about copying and/or modifying your works? Do you require attribution?

If you don't, a lot of people (myself include) will naively (and possibly incorrectly) assume that you intend all of your code and documentation to be released under a permissive (MIT or BSD-style) license.
