Is there any work being done on getting multiple views in a single HTTP

I just finished my first significant webapp with couchdb and one of the
things that was a little annoying with a javascript client was all the
nested async callbacks required to get all the data required for a
particular function to process.
Sometimes this was 3 or 4 nested view lookups, and gracefully handling
errors is difficult. It would be much easier if I could pack them into a
single async call to couchdb then handle errors or success just once.
This isn't really a critical feature since it can be done with multiple
requests, I'm not even sure it has the performance benefits that the
multi-doc api has ... but it certainly would be handy to have around when we
need it.

You can write some generic javascript to execute multiple parallel
queries, calling a single callback when all of them return. Here's a
thread with several different approaches:
