Dear Juliusz,
Lots of thanks for addressing my review comments so quickly.

I have looked up the -07 version and it addresses my review comments to the maximum possible extent.
In particular, I accept the fact that my question about fast local protection with BABEL cannot be answered without additional investigation: such investigation is clearly not part of the applicability draft.
And I also accept the fact that management aspects of BABEL are still work in progress.

Regards,
Sasha

I forgot one of your points.

> 5.       Last but not least, a few words about manageability of BABEL would be
> useful IMHO. 

People are working hard on monitoring and manageability:

  - Barbara Stark and Mahesh Jethanandani are working on manageability
    within the IETF framework;
  - Nexedi are working on dynamic reconfiguration of interfaces by an
    external cross-layer (2->3) monitoring agent;
  - a number of people are working on monitoring, both by a human operator
    and by an external software agent:

        https://github.com/kerneis/babelweb
        https://github.com/Vivena/babelweb2
        https://github.com/tcatm/mmfd

However, none of this work is finished yet, and, given the wide range of application domains of Babel, I do not feel comfortable to give any definite advice about management.  I have therefore decided not to say anything in this document.
