Yeah, this is really quite unfortunate, especially since the
alternative approach doesn't appear to be forthcoming.

I'd prefer Eric's approach over what Herbert is proposing, as the
former is available today and only addressess problems that are
actually known to exist, rather than handwavy claims about what future
developments in IPsec or h/w crypto accelerators might make meaningful
use of.
