A big +1 to what daniel said,

If f2f events are becoming so important & the only way to get things 
done, IMHO we should really start to do some reflection on how our 
community operates and start thinking about what we are doing wrong. 
Expecting every company to send developers (core or non-core) to all 
these events is unrealistic (and IMHO is the wrong path our community 
should go down). If only cores go (they can probably convince their 
employers they should/need to), these f2f events become something akin 
to secret f2f meetings where decisions are made behind some set of 
closed-doors (maybe cores should then be renamed the 'secret society of 
core reviewers', maybe even giving them a illuminati like logo, haha), 
that doesn't seem very open to me (and as daniel said further 
stratifies the people who work on openstack...).

Going the whole virtual route does seem better (although it still feels 
like something is wrong with how we are operating if that's even
