Protocol document update

I've submitted an update to the protocol document.
Until it appears in the I-D directory, a temporary copy
and a diff is available from here:

http://people.nokia.net/~pasi/draft-ietf-mobike-protocol-05.txt

http://people.nokia.net/~pasi/draft-ietf-mobike-protocol-05-from-04.html

Note that this version does not address all the issues we have
(see issue list for current status).

Best regards,
Pasi
