Eventually (okay, hopefully) large multibots will be possible.
Then each bot would be like either a pivot or a connecting dob, making larger shapes.
Like, imagine a line of robots tied together.
0--0--0--0--0
Now, add another, and connect the two at a single point.
....0--0--0--0--0
0<
....0--0--0--0--0
Voila, you have an interesting shape on which behavior can develop. That's the goal anyway. Multibots are still having a hard time organizing themselves.
