Training SharePoint 2010 Developers

And my friend Shay Petel is asking a serious question - when doing sharepoint training - do you start with sandboxed solutions so that you can use them during the course, or do you only get to them after teaching people how to develop web parts and other solutions using the standard WSP deployment mechanism? This is a big question that us trainers need to tackle. This whole developer training for sharepoint is going to blow out of proportion for us in the next year - from being a 5 day course for sharepoint 2007, I think we are going to need a 10 day course in 2010, and that may not be enough.
That said, I think that things like visual web part development significantly reduce the training time required - since asp.net developers will not have a problem with the learning curve any more...
