I thoroughly enjoyed the performance of Republic111 at the Live Code Festival.  Republic is a SuperCollider library that allows collaborative coding, there is a shared window where performers can pass code and messages.

Is there anything similar in PD?  I imagine a shared PD canvas where performers could drop or copy a patch, or where PD messages and audio could be sent or received.  My plan is to start with NetPD and experiment with multi-user collaboration.  Has anyone tried Republic style collaboration in Pure Data?

Thanks,
