mobiles: WALL4PHP and Drupal themes
I think this topic may be interesting for developers working with mobile devices.
There is a nice framework called WALL (http://wall.laacz.lv/) which was designed to create mobile independent content (you don't need to worry wheter user's mobile support XHTML or WML or anything else). There are also many other abilities of this framework.
I would like to build a Drupal theme which will be based on this framework in order to be mobile independent.
Did anybody also interested in such feature ? If so, I would like to gather ideas, suggestions, requirments to build something usefull for community ... may be WALL&WURFL is not so good and you can suggest any other solution to achive mobile independence?
Thank you.

Although it doesn't do
Although it doesn't do exactly the same thing, have you also checked out the HawHaw PHP class and proxy, at http://hawhaw.net/ ?
I am not familiar with
I am not familiar with HawHaw. Thank you for the reference.
I'm about to start developing a template/module for Drupal which will be based on something like HawHaw or WALL2PHP or may be anything else. I would like to discuss it with those who are interested and know something about it. So, the question I'm facing with is "what to use as a base?"
At this point I have HawHaw and WALL2PHP ... lets try to compare them ...
I know that WALL2PHP stores all mobile capabilities in a big XML file which is parsed only for the first time and then parsed data is stored in lots of small PHP files each of which will be included depending on a mobile model and browser. You can create XML patches for main storage to extend mobile database. You can then reparse this data to update mobile cache.
How does HawHaw do the same thing ?
