Good question.  If AM is mining in a pool that multi-mines other alt-coins, or solo mines, we may as well take advantage of that.  If they get paid out to shareholders, then each shareholder would need to give friedcat a payout address for  the other coins though, and that might be an unwelcome headache for him.

However,if AM does get the alt-coins though, and does convert them to BTC, it would be nice to get the official reply about that...
