It may be possible to use LIRC via a soundcard input with the existing
3.5mm connector, but this depends on how much of the IR circuit is in
the head of the eye. You could also try using a 3.5mm audio extension
lead from the backend to the frontend but this may introduce
unsatisfactory latency and mean a cable needs to be dropped between
the two systems.
It will probably be quicker to either build a homebrew serial IR
receiver (schematics on the lirc.org site), buy a pre-assembled one
(such as zapway.de), or get hold of a USB IR receiver. It's likely
most of the IR components of the eye could be reused if you go the
homebrew route, but I haven't yet taken one apart to see exactly
what's in it.
You can still use the Nova-T remote with the homebrew receiever -
however this also allows you to use many other remotes with your
frontent, whereas the Nova-T card/eye limits you to using RC5-based

Yes. The LIRC website (http://lirc.sourceforge.net/remotes/hauppauge/)
carries remote configurations for most if not all Hauppauge remotes.
Hope this helps,
