[GeoJSON] Current state of the RFC

Did we ever find a solution for multiple geometries?  I'm fine if the 
answer is 'geojson does not handle multiple geoms', and I just end up 
throwing a well known text string if I get two geometries.  But it'd be 
nice if there was a note somewhere on the RFC about this.

As for Multi's, I'm fine with an RFC 2 plan.  But again I do need to do 
_something_, as I have data that comes in that format.
