It's also bad that there is little or no integration of intermediate
system vendors with end system vendors (or vice versa), because that
results in insufficient sharing of information between those two
industry segments. The IETF should be facilitating information
exchange, but it isn't working as well as it should (otherwise we
wouldn't have these problems, right?).
it's not clear that the problems are caused by lack of information
exchange, given time-to-market pressures that cause folks to ship
product now and deny causing problems later.
