Well, if I need it and I have nothing more urgent to code and nobody else
is working on it or the person working on it is being too slow for me, then
I'll do it.  That situation has not arisen yet :)

The VSTa drivers don't, which is why I recommend them to start with.

The ABL code is not a good example of how HW access works in alliance.  It
doesn't run under alliance, after all.  Please don't look at it if you want
to learn that.
