Ask away. There's plenty for everyone to learn in this thread.

It is a notational technique that is integrated into the design
and implementation of the compiler, language, and the runtime
libraries to provide for a way to re-use libraries in the face of
many obstacles. (Like not having source, bugs present within the
libraries, etc.)
Miro and I have been using it in a somewhat different form though
to separate out different aspects of objects and their behavior
into clear and concise pieces, which are then grafted back
together and form a single class.
The end result ends up being largely the same. I'll have
questions down below about how you do this in your system.
But, if at some point, we decide to remove an interface, all that
we need to do is remove one of the files that implements our
extension to the rest of the system from the build system and
re-build the relevant library, and we've now removed that
entirely from use. We didn't have to go crawling around lots of
places and remove bits and pieces from here and there. This is
somewhat similar to some of the tools that exist for Aspect
Oriented Programming and Subject Oriented Programming which allow
you to isolate chunks of code that cut across a number of classes
into a separate set of files, which are then put together by the
tools (like Aspect/J). Of course, I can't speak to how this may
or may not be similar to the tools that you are using. Maybe
your tools do all of this for you as well?

If all tools were so perfectly safe, we'd have no recourse when
we actually needed to do something. What would happen if we
should need to binary patch a component out in the field? Say,
we have a running server, but we don't want to have downtime. We
need to quickly replace a buggy piece of code. Without the
ability to perform runtime loading of code, how would you propose
that the code be replaced without incurring downtime? Try to
avoid the temptation to respond that downtime would be preferable
to taking the chance that one might hang themselves by having
this type of freedom. :) It is the job of a software engineer to
know what their options are, what the problems are and to come to
an appropriate choice.

So, how exactly are you composing these interfaces? What
mechanics are you using? Is this C++? Are you using some custom
tools? How are you writing contracts? What are contracts
written in? Can you provide an example? Is this tool something
that we can look at?

Well, explain! I -know- that I won't believe "no bugs". After
all, if the tests claim there are no bugs, I don't think I'd
still trust it as I don't know if:
* Tests were incomplete
* Underlying system problems (can't do much about this)
* Tests were bug-free
* Testing harness was bug-free
* Did the tests cover data input? Did they
account for a malicious user? Did they cover
all of the relevant cases there? (Can they
cover all of the relevant cases?)
(But, I do believe that testing and automated test suites are the
only way to be assured that something does indeed work. But, I
still assume that it has bugs.)
As an aside, it often isn't clear that you've seen what you're
saying actually work: "He wanted components to be absolutely
opaque." Were they? If not, why not? If so, how did the people
using those components fare with them? Did they run into
unexpected behaviors? Was everything completely clear to them
from the documentation and the contract? Did that include the
memory usage patterns and performance profile of the component?
