That would be really something. The reliability problems are what is prompting our switch away from CAN/Jaguars to Victor 888's for 2013. The amount of time we spent pulling up the 2Can webpage and troubleshooting intermittent connectivity problems was far too great (it's really difficult to know the true source of the issues - it could have been anything from a bad connector, as some of our Jaguars shipped with bent connectors, or something more complex). That's not to diminish the benefits of CAN, but our experience with it was less than ideal.
