My understanding is that XORP Inc. holds the copyright of (most of)
the code in their corporate repo, which enabled the change of license
terms from BSD to GPL in the first place. In theory, this allows them
the flexibility to release their commercial product under a different,
non-GPL, license.

However, there are no copyright assignment or copyright disclaimer
required for community enhancements or bug fixes (as there is for
FSF/GNU projects).  IANAL, but I believe copyright of those would be
considered retained by author/contributor, with implied distribution
rights granted under the GPL.  So I would tend to agree that changes
taken from the community SVN repo going forward would remove any
flexibility to distribute the corporate product under non-GPL terms.
