Cool.

Not at all.

No additional permission is neccesary. The release-license.txt covers
all rights (Essentially, "Everything") and restrictions (copy of the
license in the documentation or copy of the copyright notice with the
source code) that you have as a licensee of OpenLayers.

Absolutely. If you're giving them the code to OpenLayers (plus your
modifications), you just need to include a copy of release-license.txt.

Of course, we in the OpenLayers community are always interested in
seeing your code, solutions, etc. as well, but the only legal
requirement you have is to include a copy of the release-license.txt
with whatever you give to other people, either source code or
documentation: no additional claims, clauses, disclaimers, or permission
is required.
