Under the OVPL the ID is special.

Consider this case:

"ID" distributes to "B".

"B" creates a derivative consisting of additional source code modules, 
and distributes them to "C", but then "B" goes out of business.

"C" uses "B"s improvements and distributes a binary, but not sources, 
to "D".

Can the ID sue "C" to get "B"s improvements?  Not under the GPL.

Secondly, the GPL requires the distribution of the source code
for the version you distribute.

The OVPL requires the license-back of "each Future Version".
This is way more intrusive and can be used to get at versions not
even ready for production.  Under the OVPL, the ID can demand access 
to CVS repositories weekly, daily, hourly, intruding and spying on the 
efforts of competitors.

The more I read your explanations of this concern, the more I think
the OVPL is a wolf in sheep's clothing.
