I\'ve been asked to research the ability to publish Access solutions directly to SharePoint as demonstrated in the demo below.

Yes, there's some excellent discussion happening with Albert Kallal and others on this topic in the newsgroups. See my blog postings on the topic of SharePoint and Access 2010. I've given you a link to the SharePoint tags as I will be blogging any additional discussions in the newsgroups using that tag. So keep checking back every week or two.
Also I believe Access 2010 is now available as a public beta this week so you can download some or all of it yourself. Visit Technet/MSDN.
