We're discussing it with Glance community. Today there will be an IRC
meeting and I'll present my plans there.

Absolutely correct observation! Unfortunately there was a hitch in the
service development caused by problems in the organization of my previous
employer. Now I try again to put the project on the right track. At least
Nokia will use Glare in production and allocates two people on it. In
addition, I received a notice from a few people who are interested in
contribution in Glare, I'll call some of them:

Geetika Batra from Red Hat
Dharini Chandrasekar from Intel
Darja Malyavkina, independent
Danil Golov from Samsung
Kairat Kushaev from Mirantis
Hemanth Makkapati from Rackspace

I think we should ask them to confirm their agreements in this thread.

Finally I'm going to announce that we'll apply under Big Tent till the end
of January.
