Pointer Events implementation hackathon - week of July 25th in Redmond

In preparation for shipping Pointer Events in Chrome, we'd like to do an
implementation hackathon F2F this summer with the primary goal of
identifying and understanding outstanding differences in implementation
behavior and their impact on web compatibility in practice.

The plan is for engineers working on implementations of pointer events
(browsers or polyfills) to spend a couple days at Microsoft headquarters in
Redmond, probably July 26th to July 27th or 28th. Details and a rough
proposed agenda are in this document
<https://docs.google.com/document/d/1b8aJOJcGXakstFJslKl87QwvlFHhHwGbQfJwnUTBBHg/edit#>.
Feel free to suggest other agenda items.

Obviously any spec issues will be taken to the WG as normal (discussed on
GitHub or F2F at TPAC in September).  So this isn't a formal W3C F2F
meeting, really just a gathering of implementors.  Anyone else interested?

Thanks,
   Rick
