Use a pair of WiFi cards, add directional aerial if required.

I guess you can use,

USB-Bluetooth adapter on both the PC's.
Then they can communicate as any other blue-tooth devices.

I also wanted to do this with a pair of Rx/Tx 433MHz modules, but need help in the protocol for transfering.
The problem is, if we send the data as it is, the modules lose sync.
I read a page on using 5050Character method of data transfer but its not explained properly.
Can someone explain this protocol.
Here's the link to the page:

1>
It is better u use RF Encoder and decoder chips available from holtek.
this will make your life simple.
2>
And few ready-made RF modules with inbuilt UART are available u can use that also.

I was talking about those RF modules itself.
What I need is a protocol such as the '5050 character' protocol to send and receive data.

Read my PIC RF tutorial - it will explain your problems!.

Thanks Nigel. I'm going to try out your tutorials.
