Hi Evan,

Thanks for the heads up.  I agree with your decision on spice models.  I
see no viable path forward for KiCad to provide a spice model library
given licensing issues and the complexity of generating accurate spice
models.  Even the manufacturers frequently get it wrong.  There are
other solutions.  LTSpice accepts URLs to spice libraries with the .lib
command which it will download at run time.  Maybe we could provide
something like that in the future.

Cheers,

Wayne
