Holy crap!
HOLY CRAP!
@cloud fodder and @BITKARROT integrated hive talk with the staircase #cordn client!
HOLY CRAP! IT IS SO FRIGGIN' GOOD!
MLS ENCRYPTED CALLS!!!
I haven't tested video calls yet, but it is built on the same stuff at #hivetalk so I have no doubt it will work.
If you're looking at a new alternative for #cornychat type voice chat, this is it!!!
Web, android, Linux, and iOS PWA (needs more testing, so come help!)
