Hi,

There are many interesting discussions here and I'd like to comment
later. But I hasten to add one point quickly.

Yes, the SAP problem is well known and has been discussed many times.

We have promoted our channel announcement system called Channel
Reflector (CR). Of course, it's free to use, and you can install it in
your site if you want.
Please visit the following site and you can register your contents
after you get your account.

http://www.channel-reflector.net/

If you want to announce site-local content inside your network, you
may want to install the CR package in your site and register the
site-local content with "local" label in your CR. Then content
information labeled with "local" will be appeared only on your site
CR. If you register global content information without "local" label
in your CR, the global content information is announced (i.e.
automatically synchronized) among other CRs and any user who accesses
to any CR can see the global content information.
