Close enough. :)
(Caveats: IANAL, but I am kinda the 'legal guy' on the mailing lists.)

There are two real conditions to using OpenLayers, from the BSD license:
They boil down to:
* Include the OpenLayers copyright notice, in the source or in the docs.
(This is taken care of for you by our build tools.)
* Don't use MetaCarta's name as an endorsement.
The rest of the license is just a legal wrapper around these conditions:
there are no limitations as to what you can do beyond that. (This
includes, for example, the outright selling of OpenLayers, rebranding of
OpenLayers, including OpenLayers in any product, etc.) The license is as
open as we can make it: there should be no legal reason why OpenLayers
can't be used in your project.

All of those are great *social* things to do, but none of it is legally
required by the license: we always appreciate the help, but we accept it
as much because it is offered freely as for any other reason :)
I agree that all of these things are valuable, and great for the
community, and we very much appreciate them. I look forward to

There is technically speaking, one minor addition to the BSD license:
the bold on http://labs.metacarta.com/license-explanation.html#license
outlines what it is. However, most legal advice on the BSD license
appears to indicate that this technical change (adding these words)
actually doesn't change the meaning of the license in any way: it simply
means that the license explicitly states what is thought by at least
some lawyers to be implicit in the license.
This change should not affect your usage of the library in any way. If
you have concerns about it, I can explain further.

http://trac.openlayers.org/wiki/HowToContribute has complete
instructions, which apply to corporations as well as individuals.
We look forward to your continued participation in the community!
