[Uni-verse] Press release

[Peter Becker, II]

Hi

To my understanding, besides Luddes description of academic achievment, 
we also present *a complete system* (with dev like diffraction still 
remaining, and lots of way to go before we have an 
off-the-shelf-software package) to the *industry*, which is what the 
press release conveys in the scenario. So the *breakthrough* is also to 
be understood in relation to industry.
