VNC Client written in ActionScript 3 / Flash Player 8.5
Check this out. Darron Schall has put together a Flash Player 8.5 VNC (Virtual Network Computing) client with ActionScript 3. Basically, it is a remote desktop client that allows you to view and control other computers remotely.
Darron has a good post up explaining what new features in Flash Player 8.5 / ActionScript 3 made this possible.
You can find more info on the VNC client over at Darron’s weblog.
If you want to download and play with ActionScript 3 (via Flex Builder / mxmlc), you can grab it from Labs.
