[LAU] Motu 1248 - Full success

I just bought a couple of Ultralite AVBs the other day since I got a really
good offer.
Have not received them yet so I have not tested them.

I have been following for some time the development of the openAVB project
and I really hope this standard is getting more widely spread.

What I cannot understand (well I can understand but not embrace) is the
fact that every vendor except AVB-switch vendors have their own
implementation and by design make their products compatible only with its
own brand. The point with a standard is IMHO to make products able to talk
to each other. Motu apparently enabled talking to some Avid
 equipment some time ago with a new firmware but non-Avid brands are not
compatible AFAIK.

I guess this is only marketing trying to protect their own brand more than
a pure technical decision but correct me if I am wrong.

Do you guys think that AVB devices "firmware" easily cold be changed by the
vendor to accept and cooperate with other avb streaming equipment ?

Do you think it is possible to reverse engineer the vendor specific
protocols like for instance the FFADO project has been doing with firewire
to make future openAVB implementations for the linux kernel if one is using
appropriate hardware (intel i210 or similar) ? Or is this already possible ?

Best regards, Anders
