Poking around Amazon, I found
http://www.amazon.com/exec/obidos/subst/delivers/delivers-signup-books.html
and
http://www.amazon.com/exec/obidos/subst/delivers/delivers-signup-combo.html
which is a combination of recommendation/filtering a la Firefly
and notifications via email like Outlook lets you do. Cool!
Certainly a scenario to consider for Internet-scale event
notification... so we have:
1. Presence updates (e.g., Ding! or ICQ)
2. Group relays (e.g., Chat or instant messaging)
3. Content pushes (e.g., sports scores or stock quotes or mailing lists)
4. Interapplication communications (e.g., document modifications)
5. Intraapplication communications (e.g., object RPCs)
6. Event traps for network management (e.g., "printer out of paper")
7. Periodic recommendations (e.g., personal notification services)
These applications can all make use of custom filtering, aggregation,
and forwarding services. Any other scenarios we're not considering?
I discovered this little notification scenario in the ack after buying
three Stereolab albums from Amazon because I'm too lazy to go to the
record store, as per a cool cat's recommendation. Note included below
for archival purposes.
