Just my 2c.

- It would be interesting to get some bird-view information
on what C APIs corosync and pacemaker currently provide to application
developers (one immediate use-case is in-app monitoring of the cluster
events).

- One more (more developer-bounded) topic could be a resource degraded
state support. From the user perspective it would be nice to have. One
immediate example is iscsi connection to several portals. When some
portals are not accessible, connection still may work, but in the
degraded state.

Best,
Vladislav

  That would be the perfect opportunity for you to convert users to Suse ;)
  
  I´d prefer, at least for this round, to keep dates/location and explore
  the option to allow people to join remotely. Afterall there are tons of
  tools between google hangouts and others that would allow that.
  That is, in my experience, the absolute worst. It creates second class
  participants and is a PITA for everyone.
  I agree, it is still a way for people to join in tho.
  
  I personally disagree. In my experience, one either does a face-to-face
  meeting, or a virtual one that puts everyone on the same footing.
  Mixing both works really badly unless the team already knows each
  other.
  
  I know that an in-person meeting is useful, but we have a large team in
  Beijing, the US, Tasmania (OK, one crazy guy), various countries in
  Europe etc.
  Yes same here. No difference.. we have one crazy guy in Australia..
  
  Yeah, but you're already bringing him for your personal conference.
  That's a bit different. ;-)

 Personally I'm interested in talking about scaling - with pacemaker-remoted
 and/or a new messaging/membership layer.

If we're going to talk about scaling, we should throw in our new docker support
in the same discussion. Docker lends itself well to the pet vs cattle analogy.
I see management of docker with pacemaker making quite a bit of sense now that 
we
have the ability to scale into the cattle territory.

 Other design-y topics:
 - SBD
 - degraded mode
 - improved notifications
 - containerisation of services (cgroups, docker, virt)
 - resource-agents (upstream releases, handling of pull requests, testing)

Yep, We definitely need to talk about the resource-agents.

 
 User-facing topics could include recent features (ie. pacemaker-remoted,
 crm_resource --restart) and common deployment scenarios (eg. NFS) that
 people get wrong.

Adding to the list, it would be a good idea to talk about Deployment
integration testing, what's going on with the phd project and why it's
important regardless if you're interested in what the project functionally
does.
