Challenge: How to control Windows 7 PC with wireless 2nd monitor?

[Mikeee]

Hi guys!

MY Name is Rene and I'm totally new to the board. I would like to start with a nice challenge

Setup: Media Center in livingroom with Windows 7 + 47" Sony LCD HDTV

Controllers: Dinovo Mini (small wireless keyboard)

Usability: I watch digital TV + DVD's + MPEG's + Youtube (etc.) via the Media Center. I also use it to check my e-mails and to browse the web.

Irritation: Using the small Dinovo is a pain in the (_x_). Working with a normal wireless mouse and keyboard in no option (kids...). When my wife's watching a DVD (or whatever), I can not check e-mail or browse the internet simultaniously.

Challenge: I'm looking for a solution to control the Media Center when my wife is playing a DVD or watching TV.

Whislist to keep in mind:
• wireless(!)
• touch screen (or touch screen + integrated keyboard > not to big)
• needs to be able to be 'plugged' onto my Media Center as a secondary monitor (otherwise it'll interrupt the movie on the LCD). <Nice challenge...to plug something wireless...uhuh...>

No go's: Remote Desktop and/or TeamViewer (or look-a-like's). Because the interaction-delay is unacceptable and it only offers the possebility to take over the main screen (LCD) - as far as I know.

After some research on the web, I'm unable to find a working solution?

Is there anyone with a BRILLIANT idea that suits my needs??

I'm looking forward to hearing from you!

Regards, Rene
