How to run a session where players can compete/fight one another instead of a default 'party'?

Like the title says I've run into a design problem mentioned in title, but first a small explenation: i'm designing a experimental RPG system for a roll20 game to somewhat simulate the exprience of my favourite populair manga webtoon: "Dice: the cube that changes everything" I've already thought out how they can each have their own secret objective and hidden cards through roll20. But i'm still trying to think out how to effectivly run the game with every player doing seperate things from others (location wise) from time to time especially when they are hostile towards each other (they can be friendly though as well). Some thoughts: the problem is that it would bog/slow down the game incredibly I think. Perhaps im trying to much to have it realistically too much. Perhaps I should force the players into factions? The players against npc (factions) such as in normal RPG games. I'd rather have the option to be able that they (player characters) go to seperate locations I think. The story line doens't excatly allow for a normal party that meets in a tavern or anything. (And it's a modern game not fantasy.) Any advice is very welcome, happy gaming!

I ran a similar campaign awhile back. It involved A LOT of one on one sessions. My only suggestion is to treat the world as a living world that X players exist in, instead of trying to do group sessions.

From a technical standpoint, Roll 20 can manage everything you're mentioning.  You can create handouts for each character's secret objective, that only that player can see.  You can create a card deck, and deal specific cards individually to players that other players wouldn't be able to see. As far as them being in different locations, you can do that as well.  Rather than moving the entire player ribbon to a given map, you can grab their avatar (at the bottom of the screen) and drag each player to their own individual map.  You can even whisper to individual players with the new Roll20 Beta audio system. But, if you're doing a lot of that (whispering, I mean), it will mean a lot of downtime for the other players, so that might tend to slow down the game a bit.
