Sharp eyes.  :-)  I should have left IRedundantService out of it --
that's just a detail of our implementation.

Our client-side code looks for primary=true if IFooService is an
IRedundantService and doesn't look for that Entry if not.  This has
allowed us to change our mind about whether a service should be a pool
of equals or a primary-backup hierarchy without changing client-side

I'm glossing over a ton of the details (like that the primary=true
filtering happens client-side instead of in the registrar), but I think
you can see what I mean.

Hi Chris,

What is the purpose of "IRedundantService".  Surely "IFooService" could
join the groups of all the other "IFooService" services?

Interesting none the less though.

Thanks for sharing.
