Unfortunately I missed the talk, but on the other hand Gromov have just produced a new paper called 

**Manifolds : Where do we come from ? What are we ? Where are we going ?** 

It can be found on his web page. From the title I guess there could be some intersection with the talk. In particular in section 11 called **Crystals, Liposomes and Drosophila**
Gromov is speaking about  "Markov quotients". This sounds like a way to produce "spaces" (generalisation of manifolds, I guess).
