Google Transit Data (GTFS) and Corona

Has anybody had any experience using GTFS and GTFS-realtime data with Corona. It appears that the realtime updates are encoded as Protocol Buffers which seems to have 2 lua implementations: protoc-gen-lua and lua-protobuf. I am not sure how these could be implemented into a Corona project.

I am looking to build a bus tracking app within Corona which will require access to these feeds.

Any advice or ideas would be greatly appreciated.
