issue #16

hi all, 

i guess we can close issue # 16:  
"Can the protocol recover from situations where the only sign of problems is
lack of packets from the other end?"
http://www.vpnc.org/ietf-mobike/issue16.txt

as a conclusion of the discussions we said:

- mobike defines a mechanism to test connectivity along paths. 
- both peers might use input from other sources to detect a failure (e.g., a
local link failure)
- based on this information mobike might decide to switch to a new address
(if available).
