This is what we have asynchronous backend communication for.
1.) a complex / time consuming query is initiated asynchronously on the server
2.) when ready, the server notifies the client that he can fetch the data now
3.) Ideally, we'll have a xml-rpc service or similar on the backend that 
pre-processes all data on the server in exactly the way the client wants it, 
and delivers that data then. Despite the xml overhead we can still archive 
less network traffic and better performance that way. We could even get rid 
of the pypgsql dependency (and mxDateTime dependency) on the client side that 
way.
