Randy ... I'm running a couple of weeks late. You can see an extremely simple demo at donbaccus.com - the first two tabbed pages are portal pages, the second two standard acs-subsite "group-master" (tabbed-style) application pages.
I'm hoping to tie stuff off by the end of the week for folks to play with.
Oh, the calendar portlets at my site don't work well ... they make innappropriate .LRN-ish assumptions which I haven't taken time to fix, yet, which lead to broken links. You should be able to play with the forum portlet and test forum though.
