I need to push messages to clients stuck behind a firewall. Existing solutions use polling of various forms. AMP would be perfect but for the 64k field size limit. There has been a previous attempt to address this (https://github.com/twisted/twisted/pull/1417) however this was reverted with a request to split the PR into the type annotations (presumably uncontroversial) and the protocol changes. The original contributor has done the type annotations (https://github.com/twisted/twisted/pull/1459) but they seem to be in "review queue hell" Can someone take a look and either merge it or specify what further work needs to be done? With regard to the protocol changes there was discussion of using netstrings. Is there any interest in a AMPv2 based on netstrings? Ian
