We could add a Bounty section to our web site, maybe we could even
change the bugtracker to mark bug reports / feature requests which
have an offer in $$, part of that money could go to the fixer and part
to the organization / maintainer.

I have no experience on this field, so I can't say how hard that would
be especially from the legal / fiscal / point of view, also I wonder
how much that would work from the economical point of view.

Also when money is involved things tend to get nasty, and that could
issue frictions between devs, that's maybe a necessary evil if we
want to continue to have a dedicated person to the project.
