I did some looking, but I didn't see a SF question directly related to this.
I need to find a platform for internal/LAN use only for chat and desktop sharing. We got a lot people having to get up and walk over to another person's office for simple items, and we could save a lot of time collectivity if we had a solution where we had a client app similar to gchat or AIM, where one could right click a name and request a desktop sharing session (to or from).
This wouldn't be for product presentation or long training sessions, and wouldn't need more than 2 people in the session. We use GoToMeeting for this.
I've looked at TeamViewer, and they got the features I want (plus a lot more features that wouldn't help) and seem more geared to large enterprise support, and it is not exactly cheap.
Also looked at OCS some as well, but it seems heavy for what I am trying to do. I don't need anything relating to phone usage. If the general opinion says otherwise, I could talked back into OCS if I am wrong about weight of the product.
We use GoToAssist for remote support of clients (which I am a fan of), and I don't it fits here, correct me if I am wrong.
All the workstations are XP/7.
