Is there a preview of the API to comment on?
At the very least it should have a "GotoSource" method an
"IsPositionedAt" method and something to give visual feedback while the
dish is moving, but then my views may be biased by my own implementation.

Personally I have just one positioner, so my plugin only allows one
instance (even worse, my kernel driver only allows one device).
I think there are no more than 3 users of the plugin (including myself),
so that's not a statistically relevant sample, sorry.
