Desktop on TV wirelessly

I would like to share my desktop from my apple macbook air (soon to have mountain lion) with my networked TV (DLNA). Obviously there is Apple TV which would enable this but I don’t want to be tied to the apple platform, I may need to also share a windows laptop on the TV too.

Can someone please help. I have done some research and the only solutions that I can find are to use Apple TV or to buy a video sender (which I don’t fancy as I don’t want to plug extra dongles into the laptop).

Can anyone suggest anything other than apple TV or is this impossible?

Thanks

They don't yet appear to have the functionality you are looking for, but that may be coming.
I use this APP on my Mac Mini and it works great.

Thanks for that.

Does anyone know if there is any hardware solution without using Apple TV

Wireless HDMI is the only option I know of unless you do the apple TV thing and do VMware to run those windows apps you would need on your macbook air.

Connect your Apple TV to internet. Make sure Internet is working on Apple TV. Open Safari browser on Apple TV and start remotely accessing your Macbook or your windows laptop by using various remote support services such as gosupportnow.com, logmeinrescue.com etc.

I don't think the OP has AppleTV and even if they did it doesn't have Safari, or indeed, any other browser.

OP:
What you're asking for is a software based wireless video protocol that works on Windows, Mac and a TV. That's a big ask and not something that exists to my knowledge. I believe the most robust and platform independent solution to be wireless wifi as already advised.
