Re: Web Payments Telecon Minutes for 2014-01-08

I find always finds these minutes timely and helpful, so  thank you one and
all for getting these out. Looking at my calendar for Q1 it looks like I
will need to rely on these even more.

As far as my talk on Jan 15 in HK@Asia PKI , I will continue the outreach
started last year and will aim to drive relevant attendance, via submission
of relevant position(s) and EOIs, to the Paris meeting via the channels
