Bit banging code? It is all very vague now... Seriously, when spare time permits or it becomes part of a project I'll do that work. Otherwise I want to ensure there is a trail in the mailing list archives so that when someone goes to implement bit banging in your structure they will find these pointers and can leverage off my work or arrange to have me do it.
