Hi!

Interesting fact: list/set_meta_context options are per-export,
so, in the server we should keep context selection per client per export.

And it is possible for client to set contexts for one export and than 
proceed
to transmission phase with another one.

This is not really touched in spec, for example
"Change the set of active metadata contexts. Issuing this command 
replaces all previously-set metadata contexts"

looks like lacking "for specified export" suffix. May be there are other 
places.
