An experimental code for reading unstructured meshes in parallel already 
exist. But there is still lot of work to do, till this code is really usable. 
For the time being we cannot store unstructured meshes per time step, but 
this would be a minor change.

No.

In principal this is already possible with H5hut/H5Part. It's not really 
according the data model for storing particle data, but anyway ...

A better solution would be to implement another data model for arbitrary 
datasets. This shouldn't be to hard.

OK, let's have a live discussion on it. Would next Wednesday at 5pm CET (8am 
MST?) be OK?
