Roberto's modification is a really good step towards making OpenACS more W3C-friendly. We should move entirely towards URLs that don't have form variables when those aren't needed.
In general, our URLs for fetching single pieces of data (one message, one FAQ, one news item, one blog entry) should be of the form /package_name/view/{id}
This is good for bookmarking, emailing URLs, indexing, etc... and it's really easy to do with .vuh files. I don't think this is so much an added feature as much as a replacement for the old clunky URLs.
