Best Windows remote support / screen sharing tools?
My company uses Webex to do remote session debugging with end-users, and for internal demos and collaboration sessions. Because of the fees involved with each session, I'm curious if there is any other software available to facilitate this. I held out hope that VNC would offer some capabilities in this regard, but I need something between "share with one person" and "share with the world" functionality.
[edit regarding duplicate] I should requalify - I'm currently using WebEx, so I'm not particularly interested in for pay utilities. I'm more interested in open source utilies, particularly the use-case where I'm trying to get three internal but widely-separated developers working on the same host.
From what I've seen of the state of the VNC world, this isn't really possible, or am I missing something?
