If the online university is to be global, it would also be good to have online partners. This can be a challenge,as this Moodle sites image shows http://moodle.org/sites/. I think there is some good work going on in the sharing of open educational resources, and Peoples Uni are using Moodle.
I'd be interested to hear about it too - it looks good. It's from Novell- I wonder what their business model is. I also wondered about Openid or equivalent.
Netvibes is an excellent way to organise feeds, links and any dynamic content. Mine is a private space to public and password-protected content, and is my home page. I read your post from my forums tab, and only had to come to Moodle to post. I have used wetpaint for wikis to support workshops and talks (as an addon) but there is a risk in using 'free' services for education in that they may disappear overnight. I haven't time to watch Wesch's video (as I am on holiday in Canada) but looking forward to doing so as I loved the others.
