Yes, I thought the answer would be "no" :-|

Right, but you could control this by using a session-limit. If the limit
is hit, the LNS will send a resource-not-available-type of failure code
which should trigger a fail-over to other LNS.. The trick is now to
correctly manage this limit, I'm not sure if changes to the
session-limit vpdn-group configuration on the LNS will take effect for
existing tunnels :-|
