SoftMind,
well, it's been spoken of a few times. the great thing with the beerhouse architecture is that you only need to change the sqlClient classes and the rest will follow, so adding LINQ into the equation (altho' not trivial) would be quite simple to implement. in fact, for new entities, using a templated solution would allow you to choose LINQ/SQLServer or whatever.
my guess is that any NEW version of the beerhouse would include both LINQ and AJAX to show these technologies working in an already 'proven' framework.
