Road to stability of communications module

Communication module is facing some challenges, some of them were known in the past, majority of them were recently discovered. Issues can not be simply put into single category, they relate to infrastructure challenges (going through NAT), coupling issues that trigger conceptual/business issues, implementation errors & lack of fear by having untested / not documented code.  They also come with different level of priority. The idea behind this document is to gather all issues that comm is facing, building up a roadmap to bring stability to the module.
