Now, with 1-to–1 video and screen sharing on HipChat, you’ll no longer need to switch apps or wait for your colleagues to log on in order to talk to them face-to-face. Everything is ready within HipChat. link
I’m a big fan of Hipchat. To me, it is like the IRC for business use. Now with video and screen-share, it is even more awesome. Because sometimes when I used google hangout to communicate with my colleague, it takes up large chunk of memory.
Although the video is 1 to 1, it is a great improvement and worthwhile for my $2 per month. Now only if you integrate Google Drive or Dropbox sharing.
