irc #planning Log From This Meeting

dveditz: blassey: why "janus"?
blassey: roman god of time, space and safe passage
blassey: why the change? apparently Speedy Gonzales is not considered to be culturally sensitive
...
Mossop: Some webapps use [HTTP requests waiting longer than 5 minutes] as a push notification. Make an XHR request to your server, when it wants to tell the client something it responds
