I would like to see the Hy8002 (and Hy8001) drivers making it into the
main ipac distribution. The issue of hotswap should be peripheral (in
that you don't need the support to make it work), but I grant that it
does confuse the current code. I will pursue the issue of licencing at
this end and try to arrive at code that you are happy with. It should
be in everyone's interests (including Hytec) to have the code in the
main distribution.

Here, here.
