Hello everyone,

we're looking for a content management system to manage a large number of different mobile websites simultaneously. I have so far played around with Joomla, Drupal and Expression Engine, but neither could satisfy our needs very well.

We're looking for the following features specifically:

- capable of managing multiple sites, each on its own domain, from a single installation

- capable of content adaption based on the User-Agent header, ideally works with WURFL

- extendable, so we can for example include our own billing service

- ideally offers "beautified" URLs and other SEO features

Can be either open-source, free software or commercial software. We don't care what application server or webserver it needs to run or which language it's written in, as long as we can make it run on a Gentoo Linux system. ;)

As I'm a little overwhelmed by all the choices out there, I'm hoping that someone has an idea and can tell me which software might be suitable for our needs. I really appreciate all the pointers I can get.

Cheers,

Alex
