Hello folks,

I've just joined the mailing list, so my questions may already have been 
answered...

- Why use the terminology "wide-area"?  It usually means a large
   area, much more than even the (small?) enterprise scenario under
   discussion.  What about re-using the terminology "site"?

- Is it assumed that only a low volume of service discovery operations
   will be initiated (per unit time)?  This "builds on" the zeroconf /
   single link case, but might be important to state explicitly.

- I guess the constraint on the number of networks has to do
   with trying to limit the traffic load from multicast packets.
   Is multicast assumed?

Charlie P.
