It's hard to choose when how unreliable isn't well known other than ,,, an X month old log.  And when "slow" is defined as waiting for a good mood from the hacker. (who supposedly hated bitcoinica)

So if very unreliable and possibly infinitely slow, I suggest you pay out a safe % to those who had the most assets.  Starting with accounts linked to users with an established reputation on the forum, you could get back BTC in the unlikely event that you overpaid.
