I would like to see PortAudio use an unmodified X11 license (widely
used, and identical to the current PortAudio license except for the
non-binding "request" clause). Rather than appearing in the license's
list of conditions, this clause could appear in the documentation, or
any other way that is explicitly not a condition of the license.
Or, if the "request" clause is not removed from the license, I would
like to see it clarified as follows:
Any person wishing to distribute modifications to the Software is
requested BUT NOT REQUIRED to send the modifications to the original
developer so that they can be incorporated into the canonical version.
