Miika,
I reviewed your changes, and sent you some typos / editorial nits.

Here are some further comments:


Section 4.9

"It SHOULD wait for all of them to respond for two minutes"

Where does this value come from?
Should this be a configurable time, default two minutes?

It seems like a long time in the context of address mobility, which you want to complete as soon as possible. Then again, on a high-latency network or overloaded server, maybe we need to wait longer.


Section 4.12.3

"but could occur on a busy server acting as a Responder"

What does this mean, acting as a Responder? Should this read "acting as a Relay"?

“The same applies also the handover
   procedures; the Data Relay Client MUST NOT include the relayed
   address candidate when sending its new locator set in an UPDATE to
   its peer if it would cause a SPI conflict with another peer.”

Is it possible then to have no valid locators here, due to the SPI collision? What will happen then?


regards,
-Jeff

    Folks,
