You can use Protobuf serialization or just write AMF serialization yourself
- depends on how much time you want to spend on it. I didn't like that how
AMF encodes strings by default and so I made some very simple AMF-like
encoder and decoder and that wasn't really difficult. I would look into
URLLoader and URLStream. Even though you may find ready made tools for
creating SOAP services, soap is very bloated, normally it would consume many
(many would be 10..100 times more) time more traffic then the same data
serialized to some binary format.
