I currently have two separate tables running in a single campaign world. They started at the same in-game date, and run at roughly the same speed.
I simply created two different "campaigns" for the two different tables. So, for instance, I made "Campaign 1" for the first group, and "Campaign 2" (with a separate gameplay thread, discussion thread, etc) for the second group.
The two groups recently ran into one another, and I had Group 2 migrate over to Group 1's gameplay thread while that was happening, then back to their native thread when the crossover was done.
Hope that is what you were looking for!
