I am pretty certain that Dirk changed the code to not allow nodes to get
bumped. The reason is to prevent denial of service attacks if someone
tries to connect as your node call and bumps your real connection. You
can also take out a node by logging in as the node call.

I would think some sort of crontab scheme that connects you to a backup
link for say 10 minutes and then retries your main connection. Another
would be to have your node partner set an alternate SSID as a spider
node and connect using a different SSID each time, again with a crontab
scheme.
