Hi,
For those of you who missed the deep-dive for the remote execution feature
on Tuesday, here is a recording for it.
https://plus.google.com/events/cg7prt50glrp3bd133d6u79jdm4
The first part goes over the end-to-end usage of the feature,
then we talk more about technical details (roles for different plugins,
asynchornous model, authentication, proxy selection). Finally
we share our plans for the future (although we were quite short on time
at the end). If you have any following questions, we can just start disucussion
here or in issue tracker [1]
We also did a new versions into nightlies, that reflect the code
as in state that was demoed. Grab it while it's hot
