Im glad it helped you, there are plenty of other things you need to take care of b4 using it on a live site:

A proper 301 direction is need, especially if the site is not new
Also, the way we put the cpath and pid right, while making the link shorter, expose it to various possible errors, but good thing is that these errors will not occur unless the users play with the link, and even, so no harm will be done. This mod does not effect ZC internal security mechanism in anyway, so as long as ZC properly sanitizes all the inputs as it is doing now, there is nothing to worry about.

If you happen to develop something on the current code, dont forget to post it here and I'll gladly merge that into the current one if possible.
