No. For "short" numbers, it's effectively impossible because there is no
way for disconnected clients to avoid numbers colliding.

If we allow very large gaps, we can create a disconnected system where
we had shared, topologically ordered integers by building a number like
this:

 [distance from root][decimal version of hash]

For instance, the current head of the hg default branch would be
something like:

  127751107515992812252955970235503334318557124985696233

This, I think you'll agree, is not very useful.
