Share Documents with External User using Live ID?

Question

I get this question from potential customers at every seminar we hold, but I'm unable to answer. Problem is I can’t find the pod cast or other source which described this issue.

Is it possible to share documents to external users using Live ID? That would be without placing them in Active Directory. I guess it would be possible if we already have external access via FIM for our internal users – but I’m not sure.

^{Environment: SharePoint 2010}

Answer 1

Well I would point the customer towards the share functionality in SharePoint Online. But if you want to do this custom then yes it is very possible.

Take a look at Windows Live ID authentication for SharePoint 2010 on codeplex, this would become the basis of what would be a custom page in SharePoint to server the requested file.
