hi Michael,

a brief reply now to be followed by a more in-depth one...

Note that this non-WG-forming BOF in London was preceded by a bar BOF, which was preceded by more work ... e.g. we have worked out a draft charter at some point, and agreed to do things pretty similar to what seems to be proposed in these slides. Now surely I'm missing the bigger picture here, but I'd like to make a plea to not go back to square one

This is absolutely not the intention; to some extent what we've done since London is look at the problem from a slightly different angle ("what are the architectural implications of the difficulty of evolving transport, and why is it hard to evolve?" as opposed to "how can we improve the interface to transport so that we can offer new services?"), and we've come to basically the same idea of the problem that TAPS has -- yes, indeed, the interface is part of the problem. This convergence is a good thing...

...and now that we're here, we'd like to brainstorm in Toronto about the way forward. We want to make sure the work that's been done in the TAPS effort is successful.

While it's clear that the TAPS charter as formulated addresses the same problem, and that most if not all of the various technical pieces remain the same, it's not clear to me personally that binding the solutions to these problems to a (single) IETF-defined API is the best way to ensure this work sees wide implementation and adoption. There are other paths: providing building blocks to API designers, just accepting the fact that people are already designing APIs and providing them guidance (especially on how not to break things, e.g. CC), doing one of these latter things and building an API on top of that, etc... and this is part of what we want to talk about in Toronto.

> I can imagine that we want to do more than what we have written into our charter, but what I'm suggesting is not to wait with piece A of the puzzle just because we in fact want pieces A, B and perhaps C too, and we have to still find out if/how to do pieces B and C. I'm having a hard time imagining that piece A just won't fit, whatever B and C may look like, so why not get A done?!

The charter, especially its formulation of the problem statement, is a good starting point; to borrow your terminology, I'll try to follow up tomorrow or Friday with specific suggestions on how we might (lightly) tweak A to better fit aspects of the problem space we didn't really get into either in our premeeting or during the BoF in London.

I note that the first concrete deliverable we've identified is essentially item 1 on the proposed TAPS charter; this analysis work should absolutely continue regardless of progress in forming any future WG -- indeed, formation of a working group would be likely to slow this work down, as opposed to speeding it up. Such an item could be published on the IAB stream if a WG isn't formed in the meantime. 

Cheers,

Brian
