Yep. The steps are as follows:
Get 4 or 6 or 8 people all as players in an OCTGN room and have one player load the cube. Have each player open 4 windows:
- Hidden archives is the pack you're currently holding / making a pick from
- Exile zone (not visible by default, but by archives there's a skull icon that makes it appear) is your picks (you need to manually set its visibility to only you)
- Face up archives is where you pass each pack to your neighbour
- The face up archives belonging to the person who's passing to you is where you receive your next pack. Then "take control" of it.
To deal yourself a pack, tab over to whoever loaded the cube in their R&D, take control of it, right click and "discard X" to mill 15 cards (or 12, however big of packs you're using). This will put it into your hidden archives.
To make a pick, drag a card from hidden to exile. If you set the visibility right, it won't tell everyone which card you took.
To pass a pack, right click your hiddens and "move all to face up archives". This works even when your neighbour has control of your face ups.
To receive a pack (from your neighbour's face-ups), right click it and "move all to R&D". This takes it to your R&D (not theirs). Then use "discard X" to mill it into your hiddens. (The person who loaded the cube needs to be careful to mill the right number each time, as the pack will be on top of the rest of the cube.)
When I ran a draft I made everyone take screenshots of their picks in between each pack, so we wouldn't have to restart from scratch in case anyone disconnected and crashed the room. But we got lucky.
Then repeat with the runner half of the cube. After loading the runner cube you need to load a 0-card corp deck; otherwise "discard X" will mill into your face ups instead of your hiddens.
