Are you actually willing to provide compensation, or is it sort of a "part of the project" sort of deal?
I mean, I'd be willing, but not for equity.
Equity can be worth much more if you are able to find unique, useful projects. Why would you 100% rule out considering a generous equity deal?
When you've been a programmer for quite a while, it's something you begin to understand. It's a gamble, you're working for free, and most of the time the "founder" substantially overestimates their worth in the company and reflects their ownership percentage in such a way.
I'd say about 80% of the requests I get are "you'll get paid if it works - equity style" and as most startups fail, it's not a lucrative strategy.
I don't 100% rule out equity deals, but I'd be less inclined to join one from BitcoinTalk due to it being remote and the chances of me actually accepting one in the first place is minimal.
Equity + a small amount of pay is a different story (and it being a great idea I can get behind and be motivated by). That would offset risk.
