I absolutely agree.  And it does not necessarily even have to occur with
a new network protocol.  The new generation of "network aware"
applications is re-defining the old definition of "connected" to deal
with a world where "network connectivity" is forever changing (i.e. like
mobile platforms) and sometimes only available for a few minutes at a
time with ever changing ISP's.

Take care

PS: First instance of a DHCP prototype was originally developed for a
business need by a corporation then shown to the Internet community.
