Instead of passing messages between components as in a
service oriented architecture, ...
...have the components subscribe to one another, pinging them
for updates via RSS / Atom / what have you?
Positives, I imagine:
* no need for changing component to maintain subscribers list
- no need to keep track of who-you-told-what (no per-subscriber state)
- no hassle with keep-alives, or figuring out "who died?"
* changing component needs only create a log of activities
* easy to subscribe -- just start polling changes
* easy to unsubscribe -- just STOP
* simple aggregators
- no finagling subscriptions,
- just pull from multiple sources, on demand, combine, republish
- caching aggregators replace data buses
* more accurate data regarding "who's watching me?"
- because they have to check you, every so often
Negatives, I imagine:
* poll traffic
- you get called, whether anything happened or not
- if you generate a lot of information that others **might** need,
you have to log ALL of it -- no telling when somethings going to
come, and start begging for the data
