That was their business decision to make, and in my opinion, the contracts they wrote around that thing were a mastery of license law in "how to pass the liability onto someone else." Luckily we now have open drivers for almost all of that hardware, so it's not so much of an issue anymore. Again, talk about this with your company lawyers, they can explain it all much better than I can. thanks, greg k-h
