Why does this need to be in the stdlib, useful though it may be for some use cases? As I understand it, RELP is mainly for communication between rsyslog servers, not specifically/especially for client-rsyslog communication. From the PyRELP link you posted, that library doesn't seem to support Python 3.x. Also, the fact that it relies on an optional OS package (librelp) makes it unsuitable for inclusion in the stdlib.
