A while ago, I released "version 1" of InstaTech. I'm still debating whether I want to make a serious marketing effort just yet, or at all.
So, while I'm on the fence about that, I figured I'd at least start sharing and mentioning it. InstaTech is a suite of tools for providing IT support. It has a remote control application, live chat support, and workstation management bundled together.
The website is at https://instatech.org, which is also available from the Projects menu above. On the Downloads page, there are prebuilt clients that are ready-to-use and are completely free for personal use.
The remote control app requires a server to connect the client app and the viewer, which is web-based. Using a server to relay the connections is how it's able to traverse NATs and firewalls without any port forwarding. The clients on the Downloads page use a server that I'm hosting, but for business use, customers will need their own server.
The Package Builder will allow you to create your own server install package that has the client applications included. Try it out on your own IIS server! Oh, and there will also be a huge update coming to Game Cloud soon. :)
