Bruce,
Part of my project is for some level of integration with an LMS. Possibly through Web services, as I have done a fair bit of research into web services. The other possibility would be to use RSS. Forums in openacs can now be enabled to publish an RSS feed. It might be possible for a student's portfolio to subscribe to a feed, and automatically link their portfolio to their respective postings. This might be considered a hack, as you'll need some form of federated identity management to say that a forum posting belongs to a user that also owns a portfolio in a remote system... assuming that you run dotfolio on one server, and dotlrn on another.
BTW, I've already started calling the portfolio package dotFOLIO. Mostly because it would complement the dotLRN project.
