I've studied all five pages on their site. There's not much there. It appears that OSHCA has meetings, and that's it. The mailing list link shows four messages this year. Their Principles ("Promote a globally sustainable approach") are so vauge as to be meaningless. They don't link to a single Open Source project. I fail to understand why they would be helpful to the original poster.

Either there's nothing going on at OSHCA, or they aren't being very open (in which case, open source people won't and shouldn't trust them).

Most of the discussion takes place on
