Generic Obex protocol? Do you mean you want to build an Obex server and want the interface complete so you can just select server->Respond(OK) when you get a Connect message?
Our Obex FTP Client and Object Push implementations were created since most people only want to use Obex to transfer files back and forth. By implementing them anyone can have Object Push support in their applications, without needing to know actually how Obex works. In the future we might implement an Obex server too, if there is a demand for it.
Until then, if you want to make your own Obex server you can build your own class and respond and transfer commands over a Stream. You can find the Obex reference manual at http://www.irda.org/
or possibly somewhere else on the Internet.
