Pinning to a specific revision is a good idea for production. At the moment, I want to follow bleeding edge, so I'm ok :)

Vendor branches are also cool, but require me to have all the code in my local subversion server. The nice thing about the Zend Framework bits that I've used so far is that overriding what I don't like is as easy to do with a new class.

1) Remember you can lock the external against a particular revision such as :

zf -r 555555 http://framework.zend.com/svn/framework/trunk

so ensuring it doesn't break when someone at Zend changes something

2) You might instead be better looking at :
http://svnbook.red-bean.com/en/1.2/svn.advanced.vendorbr.html

which probably provides a better approach in many circumstances; especially if you're likely to patch the ZF for your own internal usage.
