Forum OpenACS Development: Response to Portals roadmap proposal
I can say that after staring at his code and documentation for a couple of days, but further evidence comes from the fact that the ArsDigita intranet rewrite was relying on it, and extending it to make it easier to use. Reading Michael Bryzek's notes about the intranet project are what made me consider the portal application an essential part of the toolkit.
Yes, I believe that ACES has been widely considered inside aD as being a specialized variant of intranet. Given that ACES relies very heavily on portals, it makes sense that intranet does as well in 4.x.
The APM should do a nice job of making it possible to share locally implemented portlets with other sites.
Am I understanding correctly that ACS Site X could tie into Site Y's bboard (for example) and make it look as if it were an integrated part of Site X? If so, that's fantastic!
