Um, for items and unassigned BOffs you can already send them to yourself through the Mail... for FREE. It's not a pain at all. It's very easy to do. Why would I want a system that would charge for it?
The only reason such a system would be necessary is for trading commissioned BOffs. And there was supposed to be a system for that already in the works. Whether it is still in the plans or not is anyone's guess.
Note: I have been playing on Tribble for the past two weeks and I have had no problem sending the ordinary unbound items that I do on Holodeck. The only things that are blocked are the same Bound items that were blocked before.
