If a provider is encouraging to use 6to4, it will provide 6to4 relay for 
their customers: announcing anycast 6to4 relay address to them (probably 
only for them). Provider is monitoring operational status of 6to4 relay, 
traffic volume etc. plus help debugging MTU problems... Yes I know, this 
is can be done only for outgoing direction.... But if every 6to4 relay 
provider would be doing the same....

For example I used to know who is running the 6to4 relay used by me...(me 
and network operation team).  For 1.5 years I don't care much about 6to4 
relay anymore since I am using native IPv6 both at home and at work.
