[MapProxy] pbf vector tiles cachen

Hi all,

Geoserver nowadays has a plugin [1] to render vector data as vector 
tiles in the mapbox vector tiles specification (.pbf) [2]. It supports 
WMS requests with the format=application/x-protobuf parameter. I was 
wondering how hard it would be to have mapproxy handle wms-c and tms 
requests and cache the .pbf tiles. I am aware that the more advanced 
features of mapproxy, like WMS, reprojection, metatiles will not work as 
long as mapproxy can't read protobuffer files, and even if it does it 
would be a difficult thing. But I'd like the easier bits: turn a TMS 
request into the correct WMS-request, retrieve the .pbf file, store it 
locally and serve it to the client.

Any idea if this would be feasible at all, and if so how much work would 
it be to implement it?
