Conspiracy Extra packs question.
I think that each TO is going to handle this differently, for drafts in-store. I'm not a lawyer, so I can't advise on how to make a pack the property of the entire pod, but I can tell you what my store is doing:
When someone drafts Lore Seeker, they're welcome to buy any pack the store is currently selling, provided the pack is in English (because we didn't want to make everyone at the table check Oracle on every card left in the pack to figure out their pick). We don't want people bringing packs from home, given the possibility of mapped packs, and the TO felt that letting people buy their own pack gives players the flexibility they want - some will want something crazy and ask for a pack of Worldwake, some will want something familiar and ask for a pack of Dragon's Maze, and some won't want to pay another $4, or will just see a better pick in the pack, and pass the Lore Seeker on.
Remember that while the MTR don't prohibit someone from leaving a draft before it's completed, your TO has the right to refuse service. He or she might consider asking players to just be sporting and not walk with their pack of Revised, because they might not be welcome to participate in the next CNS draft if they take advantage of the TO's generosity. It sounds like you've got a pretty good community, if your TO is willing to hand out a pack of a player's choice for free, so this hopefully will just be hypothetical and not be an actual problem.
