For Approval: ACE License

If this license cannot be revised, I recommend that  OSI withhold approval. 
With a minor revision, I world agree that approval is warranted. The second 
paragraph should be revised. As it stands, I see a number of concerns under 
OSD Article#1,2, and 3 since the license appears to permit that the entire 
project may be taken proprietary by any licensee.  I doubt that this is the 
intent. IF  such latitude is intended, then the licensee world not comply 
with the OSD.  Under the BSD, this is a privilege reserved by the original 
copyright holder.

There is a significant difference between permitting licensees to 
distribute modifications or enhancements to original code under a 
proprietary license, which the BSD permits, and  permitting licensees to 
distribute the original code as a binary under a proprietary license, which 
the ACE license appears to permit.You probably mean to follow the BSD, but 
it is not clear.  Perhaps, one point of confusion may be clarified by 
replacing " proprietary" with binary.
