Less a directory of servers (to use old school language) is the problem but
working to develop a cooperative service--- unless the maintainer of the
server too will be responsible for the global monitoring service.

I think we can design things as a nice failsafe distributed service-- hey
that's what we're all about here is it not..?

If we design things "correctly" it does not matter.

A reference piece of code could be provided--- we can discuss things here what
the code would do (as a minimum its a service level ping server). People
willing to run the service would then register--- the code itself should
probably allow during installation the default to self-register and itself
ping a set of "monitoring servers" at some min. interval to announce its
continued availability-- themselves as a voluntary monitoring node. The
"monitoring servers" would sync with each other their known and registered
nodes. Other "monitoring servers" could be added as a mesh. Code for such a
server too could start off relatively simple.

With the above model they could as well.. to allow people to apply their own
quality metrics.

In the above model there is no real central site but a mesh of friendly
servers running a common set of code and with a common agreement, checking
services at agreed upon intervals and within agreed volume levels through a
number of friendly ....
