I unfortunately won't be able to attend the telecon so my thoughts
are below.

Hm, never thought of BMIs as being similar to static libraries.

To me, static libraries supply the implementation while BMIs
supply the interface as well as the "inline implementation"
(i.e., implementation that is expected to be compiled by the
consumer, not the supplier).

I think this is sensible, however, I wonder if a better term
would be "cached" rather than "distributed"? To make it clear
that not distributing module interface sources is generally
not going to work?
