I don't understand how you can expect to maintain a trademark without someone authorized to make decisions about what is OK and what isn't.
As the Foundation's legal co-ordinator, I'm sure Jean-Baptiste Soufron can handle this, with help and advice from the members of "juriwiki", our legal mailing list. Jimmy could appoint a new position if the matter gets too much for one person to deal with, and in future, we might want to consider making an IP officer a paid position, but for now, I've not seen any problems with continuing the current process of having Jean-Baptiste deal with enquiries and problems in this area.
