\iesg{The IESG intends to charter, in the near future, one or more working
groups to produce standards for "name lookup", where such names would
include electronic mail addresses and telephone numbers, and the result
of such a lookup would be a list of attributes and characteristics of
the user or terminal associated with the name.  Groups which are in need
of a "name lookup" protocol should follow the development of these new
working groups rather than using SIP for this function.  In addition it
is anticipated that SIP will migrate towards using such protocols, and
SIP implementors are advised to monitor these efforts.}
