I need a LAN based system for collaboration, training, and conferencing. The primary features I need are desktop sharing and voice conference. We would like to host internal training sessions and allow users to view the sessions from their desk and see the trainers desktop and listen to the presentation remotely. We used Netmeeting for this with Windows XP, but there is no similar software included with Windows 7. The new Microsoft solution is SharedView which is internet only. I do not want to use my internet bandwidth for these meetings. All the solutions I have found like SharedView, GoToMeeting, VYEW, etc work fine but require all the traffic use their internet server.
I have tested Team Viewer which will work over the LAN and has the features I want but the license cost is prohibitively high for a small company.
Your feedback and insight on this question is appreciated.
