Determining a root cause is distinct from monitoring a service from the 
internet, which is also distinct from testing a service on a public vs a 
private IP address.

For example, we monitor services both on internal IP address, and on public 
IPs (the monitoring server is NAT'd behind our firewall, and can monitor the 
NAT'd services).

If people are interested in a hosted hobbit monitor (bbtest-net) for 
monitoring their services from the internet (and reporting to your own hobbit 
display) ... I would consider providing such a service (at a cost of 
course ...).
