Designing a Robust Input Handling System for Games

Thanks for the link!  Even if it wasn't exactly what I asked, it was a good read and pretty helpful.

My system is quite similar to the one described, but it's nice to hear what works well for people after the fact.  I didn't however do the XML configuration file approach, but that's a good idea for user-friendly configuration.  I might have to come back and do that.
