WG,

To be explicit,

The Straw Poll has ended!

Thanks for participating, we have received 100 answers to my count at
the time of writing this. I think it has helped us all provides the
different views, and what different participants considers important.

We hope to be able to provide the chair's summary of the poll, we also
intended to provide our tabulation of the straw poll data. All hopefully
by the end of the week.

Cheers

Magnus Westerlund
WG chair
