There is currently a big SharePoint conference running in the USA and as a result of that a host of new SharePoint announcements. Here’s a few that I think may be relevant to those in the SMB market space.
External Collaboration Toolkit – this kit can be used to setup a SharePoint site on your network and have internal users access the site using their normal AD account, with external users accounts being in a separate database on the network. You still need to have a Windows Server CAL to be legitimately licensed, but this increases security and functionality at the same time. You can find out more about the SharePoint External Collaboration Toolkit from http://technet.microsoft.com/en-us/library/cc268155.aspx
GEAR UP for SharePoint – this will help you get ready to deploy SharePoint to your customer sites. http://sharepoint.microsoft.com/gearup/Pages/default.aspx
