of course you can ;)
I wrote a little script for blender so that you can send all mesh information like vertex coordinates,normals,indices and texture coordinates over zeromq to a destination you want. in real-time. in vvvv you can easily receive this data and build a mesh out of it.
the goal was to use all the modelling possibilities of blender in vvvv. you can even use blenders physic simulations in vvvv now ;)
but it is in an early state right now. it works only smooth up to ~6k vertices. but I am still working on it.
I've already tested it for a mapping job where blender was running on one pc and vvvv on another and it really helped me.
