[OpenLayers-Dev] Status with map context?

[Peter Robins]

http://trac.openlayers.org/wiki/Future/MapContext

Looks like this was discussed some 3 years ago, but AFAICS hasn't gone
anywhere since. I'm looking into doing something similar, and have
looked at both the WMC and the recent OWSContext formats, but the
problem with those is they're limited to OGC-'approved' layer-types
and also a json/js serialisation would fit OL better than xml.

Is anyone working on this?
