There was an organisation for this around four years ago, I was involved in. If you were serious about this, I think trying to get an org going would be the best way. Anyway, going back to the old org, it didn't really flourish too well. We had a semi-active IRC channel and an official org/private board that got sporadic use. There simply wasn't enough like-minded individuals to justify the organisation.
However, it may be different now. If you could find a decent group of people who are interested, go for it. If no one is interested, the demand simply isn't there and there is no point.
