You can't use the N770 as an IR remote. There is no power supplied to
the USB port. You'd have to use and external USB hub with a wall wart
for power and then it's not portable.
What you can do is use the N770 to talk wifi to your home net. Then
buy a little $100 development board like an Efika or an Atom and plug
it unto your net. Get a MS USB IR transceiver for the development
board. Run a tiny web server on the development board. Use the browser
on the N770 to get to it.
