Would it be possible to support recursive graphs in protobuf-net, as a
implementation-specific custom message extension? For example, if
protobuf-net could automatically insert an "optional int32 uniqueID =
1000" field in to each message, it could store an auto-generated
unique identifier for each object. Then, if you come across a
previously serialized object, you need only read/write the uniqueID
field and leave the other optional fields blank. The protobuf-net
deserializer could output the previously constructed object. The
uniqueIDs would only be valid for a defined scope, eg. one contiguous
wire message.

Yes, that is already on my list of things I really, really want it to do. It will inevitably be in "v2" at some point, but to repeat your point: this will be 100% implementation specific and not generically portable between platforms, so it will have to be by explicit "opt in".
