Group Play: How will it work?

[wheredoigo]

Could someone from Lonewolf give a brief overview of how group play will work? I've read the information in the FAQ and I am really excited for it, but would like some additional details if possible. I had thought (incorrectly) that we could add additional concurrent devices for this. Reading comments on this forum I can see I was mistaken.

• Do my players have to buy all of the content used to make their characters?
• Right now there is the iOS app that we use as Pathfinder character sheets, will we be able to do something similar with HL Online?

If the details on this haven't been fleshed out that's fine, but any information you can provide would be greatly appreciated.
