Editable GeoJSON in OGR is great news!

I've got a question regarding the geojson driver you may be able to assist
with. Is there any method in the OGR libraries which allow direct parsing
of a string to a  layer? (Ie, without first writing it out to a file).

I'd like to add the ability to directly paste geojson text into QGIS and
have it inserted as a feature in the current layer (like how you can
currently paste WKT text as a feature). I don't want to have to manually
parse the json (that would be a nightmare).

If I could somehow take advantage of OGR's geojson driver to do the heavy
lifting then this work would be trivial.

Any ideas?
