I beg to differ - I think that *some* of the stacks have a good design.  Do
note however that good design doesn't equate to good implementation.  A good
design has the hope of being well implemented.  On the other hand, no amount
of stellar implementation can help a bad design.  Never the less, in light
of your comment, I would like to request more specific *design* related
criticisms.

There seems to be a big push to hit the reset button on all these IB stacks
and start implementing something new.  Better in my mind would be to spend
some time figuring out the desired design tradeoffs, then picking the stack
that's the closest (if there is one) and working from there.  Unless we
spend some time on the design phase, no implementation has much of a hope of
being adequate.
