Hm.  I am clearly misinformed, then.  I thought that
the difference in impedance was what dictated the type
of injector (voltage-limiting or current-limiting). 
So you can build p&h drivers that work with
high-impedance injectors?  What would be the advantage
over building one with a low-impedance injector? 
Frankly, wouldn't you need to build a rater unusual
injector driver to get it to operate that way?

The impression I got (which could be all wrong) was
that using p&h drivers on sat injectors left you with
nothing more than a sat driving signal with a lot of
component overhead (and thus, cool components).

Maybe I should be looking at some driver circuits so I
better understand the difference.  I peered through
the archives rather quickly, but don't think I saw anything...
