Oops, I've mixed up names and you're not actually on the same team.
Sorry about that.

Still when you do upstream development please try to follow a bit
what's happening in general so that we can maximally exploit
opportunities for collaboration. That's why we have such a big
emphasis on open discussion fora like mailing lists or irc channel. So
I very much want people to jump into discussions of patches from other
groups (or even outside from Intel) if they see some overlap (or other
possible benefits like sharing learned lessons) with their own work.
