is dormant for now.

Olshansky, I2IM working group flywheel, with questions or comments.
Instant messaging (IM) services have traditionally not been integrated
into a campus enterprise IT infrastructure. Services like IRC and AOL
Instant Messenger have been widely used by university people for university-related
work, raising issues of authentication, authorization, privacy, and legal
compliance. As IM becomes an increasingly popular alternative to email,
users look to campus IT services for the same level of support and integration
traditionally provided for central email services. Popular IM services
have used proprietary protocols, and standards efforts have not been entirely
successful to this point.
Given all this, many campuses have made initial efforts toward designing
campus-scope IM services around Jabber/XMPP technology, which has benefited
from an open process, open-source implementations, a server-based architecture
well-suited to enterprise management, and the likelihood of an IETF standards-track
Internet2 is technology agnostic, and has not "standardized"
on Jabber/XMPP or any other approach. Our goal instead is to explore the
needs and applicability of messaging and middleware infrastructures to
support federated administration and the needs of Higher Education and
Research. As the work of this group proceeds it will involve the myriad
of IM vendors to explore and understand the issues exposed and how available
technologies may address these issues. Interoperability between SIP, SIMPLE,
JABBER, XMPP, AOL, MSN, ICQ, etc, are all on the table. Cooperation and
collaboration with other working groups and other bodies is critical to
the success of this working group. After exposing and discussing the issues,
this working group may determine that currently available technology solves
all the problems and is adequate for the issues at hand - this would be
an acceptable result if that should come to pass.

The I2IM working group intends to address the following sets of issues:
- The WG will research the issues surrounding enterprise integration
of IM services with respect to identity, authentication and authorization.
Where possible, it will document how to perform this integration and
provide forums where people can learn and help each other in addressing
these integration issues within campus contexts. Where appropriate,
this working group will work with the Jabber Software Foundation (JSF)
to consider appropriate modifications or other techniques for achieving
better enterprise integration.
- The WG will investigate current and future designs of relevant technologies
with respect to authorization services, and how authorization information
is transmitted and interpreted, especially between domains. It will
consider how to integrate these methods with emerging campus and inter-campus
- Based on interest and technical feasibility, the WG will consider
this range of issues for non-proprietary IM technologies.
- The WG will consider and possibly instantiate a national or international
federated IM service. It will look at feasibility and applicability
of leveraging technical methods like SAML/Shibboleth, and the policy
frameworks coming from federations such as InCommon.
