Sounds great!

We'll have an IRC meeting on Wed July 31, 18:00 to 19:00 UTC in #tor-dev
to discuss deliverables including this one.

Can you give me more details what you achieved and maybe push your
rebased branch somewhere, so that I can report your progress at the meeting?

Or do you want to join the meeting?  If so, see my earlier mail to this
list for details.

Thanks!

Karsten
