Access is just migrating to more of either a single user on a desktop or a few users on a shared database file without much security. If you want to take it to a slightly higher level, use Access as a frontend to SQL Server.
Well now it seems Access 2010 is looking to get the hooks into SharePoint in an attempt to "web enable" the Access application. There are even host sites catering to this technology. Maybe all those who were concerned Access couldn't scale can fear no more?
