[mapserver-dev] Toronto sprint hopes and dreams

Regarding the one-pass queries. Can we get an RFC in place before the event? I have some
ideas on how this can be accomplished and it would be a good idea to get on the same page 
ahead of time. I was thinking of attaching a feature cache of some sort to the result set object
that we already have. Then, if one-pass is desirable you'd stuff shapes into the cache for
presentation. The various drivers wouldn't have to be touched.

Perhaps you are thinking of something more general...
