The SL Commerce Team just launched the Direct Delivery Beta on the Aditi (Beta) grid for SL Marketplace.
Direct Delivery basically means merchants won't need Magic Boxes to hold their Marketplace items for inworld delivery. Assuming the bugs can be worked out, this is certainly a long-term good thing. At the same time, the old if it ain't broke, don't fix it rule applies. Magic Boxes, while a pain to deal with, seem to work at least 98% of the time for me. Good luck Lindens!
