The "screen shared to" window Thanks for a quick reply. I still need to test it further to see how it reacts to dual display, but we've got some situations where we've got a laptop connected to a projector running Powerpoint (the usual presentation situation, with computer showing the Presenter View, the projector showing the presentation) and unfortunately we need to be able to stay connected for the duration of the presentation to make sure everything works and to react immediately if there are issues, but we can't have the popup disturbing the presentation. On the laptop screen we can possibly live with it, but even there we'd prefer to at least be able to have it drop under the screen while the presentation is on.
I do hope this helps. From what I saw so far it seemed pretty nice. Quite a bit like Teamviewer, but of course still missing some features. While waiting I'll take a look at the rest of your offerings. =)
