I am not 100% sure on this, but you should be able to set-up a program like HIP/Girder to control remote commands using keystrokes which I am guessing could be transferred over Wi-Fi from your Nokia device using something like VNC/Telnet.

I will try to explain it step-by-step.

1. Nokia device with Irreco/Telnet/VNC logged on to PC via Wi-Fi
2. PC has Microsoft e-Home IR Receiver/Transmitter installed and Girder/HIP
3. e-Home device has the blasters installed for transmitting received commands to external devices.
4. HIP/Girder set-up correctly to interpret commands from the Nokia device.

So I could tell HIP to use Channel Up command when I press the up-arrow on my keyboard. I VNC into my PC via my Nokia device, load the on-screen keyboard and click the up-arrow button. Now you can make it do this behind the scenes I am sure with Irreco/Telnet.

Now this is just for MCE. But the same principal should work for TV/Hi-Fi/Satellite and so on, as long as you get HIP to learn/record the specific remote controls commands and set them to blast out on the specified keystroke.

I haven't tested this yet, so this is merely just guesswork. The hardest thing is getting HIP working with the e-Home device, learning the right commands and blasting out the codes on keystroke etc. Once this is done right though and working it should be very easy to get the N800 etc speaking with the PC to execute the commands.

I hope this helps
