Protobuf and Pipeline questions

["이희승 (Trustin Lee)"]

Hi Christian,

I would wrap the protobuf messages with an envelope protocol.  For example:

<TYPE> <LENGTH> <PROTOBUFDATA>

You could determine which protobuf type the message is from the <TYPE>
field.  It means you need to write a decoder / encoder by yourself
though.  It shouldn't be difficult.  Please start from the Factorial
example.

HTH,
Trustin
