Yeah, that would be great. Maybe the code-tables can be passed via 
/proc-interface to the driver. dvb-apps then could provide a learning 
tool, which generates the tables.

The dibusb-driver has its own remote-input-stuff, the cingeryT2.c does 
exactly the same, but both don't use dynamic key-assignments.

Maybe there should something like a generic rc library/module for the 
dvb-stuff (or even at a higher layer inside the kernel).

It should be able to handle different remote-control-protocols (ie. 
different rc-key-to-input-event-tables-formats, I know of NEC and a 
Hauppauge specific one (used in NOVA-T USB2), I assume there are more).

Will lirc ever be inside the stock kernel? Is lirc an option for such 
things?

regards,
Patrick.
