Unfortunately, the more recent posts I've seen from him would indicated
that, due largely to ASICs that cannot easily be reverse-engineered, a
switch equivalent or extension is all but dead as a concept. This is why
I chose to go ahead and purchase some 3560-8PCs and just move on...

That depends on the devs, and if they can continue to support future
platforms, whether it is possible or feasible. No switches yet, maybe
never, but who knows, chris has some posts where he wanted access to
6500 switches. Might be workin on it :P I hope so. Here is the site
with the history.
