Actually, if you've not heard already it seems to work fine with the new Tradeskill Depot. Items in the depo are dumped with the usual "/outputfile inventory" as long as the depo is OPEN when you execute the command (just like the Dragon's Hoard). Items in the depot show up in MCIM as being in "PersonalDepot<slot#>"
Which is fortunate, as items the the depot don't show up with the "Find Item" function in-game. Grrr...
