Dear Sylvain and BLAZAR team,

I'd like to receive your feedback on our blueprint 
(https://blueprints.launchpad.net/blazar/+spec/fair-share-lease) and 
start a discussion in Paris the next week at the OpenStack Summit. Do 
you have a time slot for a very short meeting on this?
Thanks in advance.
Cheers,
Lisa
