YAS is perlmonks, at least legally. (Check the footer on all the pages) There should be some sort of perlmonks-specific fund, the same way there's the perl development grant fund and the general fund. It's just a matter of getting someone with some level of authority to set up a separate directed fund so the donations can go there and accumulate until someone with the authority to disburse it can do so.
This'd be something for vroom, tye, or one of the other site gods to do in coordination with the YAS folks.
