Personally, I very much like the approach that is explained in this blog post:
http://happygiraffe.net/blog/2008/02/07/vendor-branches-in-git/

It's explained for Git, but the beauty of this approach is that it also works with 
Mercurial, and even better, its very simple, because it only uses the "normal" feature 
set of a version control system. No extras for subtree, submodules, subrepos, sub... 
required.   ;-)
