I completely agree, and I have addressed this fact (in netdev circles) before.

With isdn4linux, there was one vendor (ELSA?) who funded the certification/approval process for one specific i4l version. It took quite a bit of time, since they actually tested all the protocol state transitions, etc.

After this was done, this actually was a business advantage to the vendor. The stack was only certified for their card[s]. So anyone deploying i4l in a commercial environment wanted to use their cards. Obviously with passive ISDN cards, all other cards would also behave exactly identical - but they were missing regulatory approval.

Obviously, using a later i4l version and/or applying bugfixes to the source code also voids the approval, and in order to use it legally, you would need to re-certify.
