Screensharing applications I am very well familiar with.
However they are all a bit too heavy weight for what we are looking for. Want to be able to quickly share a window/application and have that broadcast over the network to a remote viewer. Very much how you would do a quick screengrab and email that to someone, but instead a live session.
This is very handy for development teams that sit in the same room where you can have someone say "hey look at this" where they can share a given portion of their desktop and quickly have someone remotely view that.
Has to work internally without relying on going out to a public internet server.
What solutions are available?
