I have done that a while ago. Its now available at https://github.com/Zero3K/connectfusion.

1. Its not supposed to be one file. Its sending chunks to a media player such as MPC-BE via pipe://stdin.
2. I made a branch that has it almost working (it just stops requesting data to send to the player after 2 minutes or so, in the case of some streams, it stops after sending chunks to the player and most streams aren't requesting data because its missing chunked encoding support in the HTTP library that it is using). The branch can be found at https://github.com/Zero3K/Tardsplaya/tree/twitch-fix. I would also like to have the ability to have it buffer multiple streams in one instance finished (the other guy got it to have a bar which shows Stream[1] with no ability to add streams and have them be buffered by it).

Remote is a program that allows the controlling of multiple computers via one keyboard and mouse. If anyone has any ideas regarding a better name for it, please reply to https://github.com/maxrigout/Remote/issues/5.

To use it to control a PC/Laptop from another PC/Laptop, do the following:

1. Choose Server in its dialog box while running it on the PC/Laptop that you're wanting to use to control the other one.
2. Click Start.
3. On the other one, choose Client in its dialog box.
4. Enter in the IP address that is displayed in the dialog box of the one being used as the Server.
5. Click Connect.
6. To control the PC/Laptop that has it running in Client mode from the one being ran in Server mode, move the mouse to the upper right portion of its screen. It should then send the mouse movements to the Client.
7. To regain control of the one being used as Server, move the mouse of the one being used as Client to the upper left portion of its screen.
