An ability to make a list be OPEN subscription to a specific set of nodes
would be nice. This feature MIGHT take the form of a new keyword on the
list control file, called SUBNODE=. By using this keyword one or more
times, a list of node names from which subscriptions will be allowed is
specified. Wild card characters should be allowed, such as to allow:
* SUBNODE= UIUC*
or
* SUBNODE= UIUC%%%
I will donate my code for wild card matching if needed, it's REXX callable.
