Your paper seems very reasonable. I've been operating a two tier open
source company for scientific applications for the past five years. I
find it an easy enough sale to an open-minded business person, if they
are looking for what I do, and they have a relative scientific bent
(the better to appreciate the open source rationale).
I find it a little harder to sell to the open-source community,
because the business strategy you've documented is facilitated by an
X11/BSD license, and people imagine the only reason to use such a
license is to take the freeware proprietary at some later date. Maybe
a concern for system utilities and programming environments, but the
reasoning doesn't apply to the two-tier open source businesses you
describe, developing highly specialized applications with no mass
market.
In the world of layered vertical applications there is not much
difference between a company paying to have a unencumbered proprietary
application developed on top of (and in collaboration with) open
source, and a company paying to have a GPL encumbered application
developed that no one else would ever care to use. Each approach can
be mutually beneficial to the private organization and the open
source.
