Actually, I asked several people to look at ethng on the wiki. I was
fairly clear that that was very close to what I wanted to commit. I
also said that I wanted to commit at this time. The only person to
actually take the time to give me feedback prior to commit was Mike.
In the future I will request commentary in a more pubilc forum and
make my timelines more specific.

Sadly, often the only way to get a real discussion going is to make
the immediacy of it relevant. To date I haven't made any material
structural changes to TCP, I've only added the hooks that will be
needed. As requested by another I will add some commentary on the
purpose of each of the individual hooks to the header file.

I have no strong feelings about naming and I'm more than happy to
follow whatever consensus is. My natural inclination is towards
shorter names but I don't identify with my function names I just need
the functionality to be present.
