A potential way to do it would be to allow specific accounts as 'box' accounts. The accounts would automatically work around the IP restrictions, but any character created on the account would be unable to obtain any experience. All characters would be permanently level 1. Thus, they could be used for item transfers (avoiding the "Soandso ripped me off!" petitions/threads) and, if you're willing to run them out there, EC mules. (Though the EC Mules would end in hilarity/tragedy when someone inevitably trains a skeleton through the tunnel)
I understand the admins not wanting it, though. Fostering community through trust. Finding someone responsible who won't rip you off when twinking an alt is part of getting to know the people on the server. If I was going to all the trouble of getting my precious stacks of spider silk off Kunark to my tailor, I would spend time to find someone who is less likely to destroy them and laugh at me.
