To say that LobeShare plans to release an online adventure game is a perfectly good lie* - it will allow developers bidding for this project to visualise the requirement. Consider something as big as the universe (visible or not, known or not, real or imagined) as one large shared database. In the "game" one can travel many times the speed of light to move anywhere in the universe almost instantaneously. The problem though is that until you've been somewhere, it makes little practical sense to just jump there instantly. You need to navigate to where you want to go based on the route there.
There are several further complications which in the metaphor of the "multiverse adventure game" lie would be :
The multiverse is far too large and detailed to pre-load all the data into every player's computer in advance, and
the multiverse is not static, as players add more detail to the universe as the interact with it, including their positions and orientations others can see.
Consequently, the Viewer would be provided with pre-fetched data to display movements in any direction, but would need to report all movements and updates to the server so that based on the direction of travel, more data can be sent through before it needs to be displayed.
* In Terry Pratchett's Discworld novel Night Watch, the monks responsible for managing and explaining time travel to Commander Sam Vimes come up with several ways to explain which they also tell him are utter lies, but "good lies" as it helps him understand. LobeShare is not about a game, but stating that it is makes for not just a "good lie" but a "perfect lie".
