Given that in a traditional 'event' draft, trades are worked by the teams on phones, I'm not sure how this aspect would change?
The issue would be if the teams still have to get a physical card with the selection or trade to the 'front desk' and I would like to think that's entirely replaceable by a telecoms/technology-facilitated direct link instead. I'm no IT expert, but setting up a secure Comms channel for these things is hardly rocket science.
