The Vendor Branches chapter in the book addresses how you can handle this in Subversion. http://svnbook.red-bean.com/en/1.5/svn.advanced.vendorbr.html If the source code is coming out of a Subversion repository on their end, and you have at least read access to it, then it can be even easier (you can just "svn merge" their latest changes from their repository to yours).
