it's not: PyROOT is based on CINT dictionaries. Are you sure btw. that the result of id() will yield a pointer to the underlying object for msg.buffer? It normally (and only in CPython) is a pointer to the python object; it will not work for PyROOT objects for sure (use ROOT.AsCObject() instead and pass that result around for those cases, but I don't know what socket returns).

Best regards,
