If this is an evolving project for a more long term venture:
Think RF, Zwave, Zigbee or even Bluetooth (short range but no real market competitors yet) for remote to base station communications ..... then convert to IR and RS232 for source control.
2-way coms will have to be on horizon very soon.
Where will you be getting clean verified working IR code sets?
do you already know IR frequency standards? Hex coding stadards?
Overall. control systems work better when coding lives on base station and remote fires trigger commands.
If this is a one off remote for your own use:
have fun .... just design for your own very specific needs.
