Alright so.

I have toyed with this idea a couple times, never really sure how to implement it, but then I decided to see if it would even be worth a shot.

To keep things simple. The idea is actually for more than one RP.

Instead it is for two, or maybe more. (Though to keep things less annoying for me, I will explain with two for the most part.)

Two RP's running at the same time. One is themed in one way, and another themed similar, but not completely. 

Through some plot element, either mysterious portals, some astral messenger or something with some originality, the characters in each RP, are able to communicate. 

So, while one group goes on their adventure or whatnot, so does the other, and while they don't really have anything do to with each other, there are odd parallels all over the place, and the participants, are able to speak to the players from opposite games. 

With such an odd setup, things could go many different ways. We could eventually find out, they have been not very far from each-other after all, and dump them all together to finally meet in a new thread. We could find out, they will never meet in person, but still effect each others lives and chances of success in whatever they are doing in their game. A character from one, could be suddenly thrown into the other, and both sides will have to adapt. An item seemingly worthless in one game, is sent to the other, and becomes vital to their success. 

So.

Just throwing the idea out there, if anyone wants to try it. 

I see how it could get annoying/confusing, but if people really care, it could be one of the most interesting and unique game(s) played for a good while.

If enough people show interest in this idea, we can collaborate as to what is going on in each game, and then keep expanding from there.
