All have been good solutions. The best choice depends on the the user's
(payer's) perspective as regards cost, ease of use, reliability and
serviceability.

Each solution offered has merit. Each offers unique features and overcomes a
different potential limitation. Only the people that will use it can shed
further insight in this, I believe...

The really super thing aboutthis is that it shows that this list can
accomplish nearly anything in the world of control design.
Now, is there anyone out there thathas venture capital connections?
