Use other technologies (such as WebSocket) in Aphlict, so it doesn't require Flash. Reasons:
* Mobile support (see T5390).
* Flash still doesn't have good support in free software/open source (though I haven't checked if this works in Gnash).
* Flash requires serving a socket policy file on port 843, which may be hard to get by corporate proxy (And corporate proxy ops team).
* Poor/late IE support http://caniuse.com/#feat=websockets (IE >= 10). However, if IE < 10 is a must-have for this feature, something like Socket.IO can be used. That uses WebSocket internally, but has a fallback to COMET for older browsers. The fallback apparently [supports](https://stackoverflow.com/questions/19903646/web-socket-support-in-node-js-socket-io-for-older-browser) even ancient browsers like IE 5.5+
