I would say the other way around
some people may only want to donate artwork once they know who they're giving it away for.

Perhaps everyone who donates artwork can nominate a charity
and all the suggestions go in a poll.
then either winner takes all or split it in a green-tokens-in-Waitrose stylee.

OTOH
if it does go the eBay route then no doubt you can specify which charity for which item and proceeds go direct to the charity of the donator's choice (as long as it's one on the eBay list).
