http://bugspy.net/ do this already- It gatheres tens of thousands of bugs.

Why should we bother again and again to install the CMS on our own? paying for LAMP provider, taking care of all the boring details of installing and maintaining the software?? Modern CMSs should take the course of CMSs like Novoya.com (my favourite). Building common web sites should be a pieace of cake even for my mom, and not a nightmare (like in drupal's VERY complicated CMS and "node" concept) I had tried many of them in my career: Drupal, Joomla,Mambo,you name it. They all suffer the need of close baby sitting (constantly be aware of new bugs and holes, backups, using the correct software versions, resolve conflicts in extensions etc). It is just not how modern service should be provided.
