Hiding behind DNA?  Gotta be thin ...

An NDA is a device to allow a company to get its act together while 
getting feedback on the product they want to release.   It is quite useful.

er ... have you looked at the site I indicated?

No, it's not.  It seems to me that given the number of applications out 
there now using their kit, that rumors of a lack of information to use 
their kit might be ... er ...  not well founded.

Ah ... Ok.  Manners, manners Vincent.

Hmmm.... I would suggest you sign an NDA with them, and learn what it is 
they are talking about to their customers, though I suspect they may not 
wish to pre-divulge information to you given what you have indicated here.

Cell is good.  Now try to program it.  Yes, it is a SMOP (

Yup.  Exaflop at 2.66 GW.  Waaa hoooo!!!!
