Hi Nick,
As I said on the other thread, it is on my radar and I have no doubt that at some point I will come up with a good solution for mobile. The jqueryui mobile stuff is also something I'm watching for part of the solution but there is much more to it and it will be significant work to come up with a good solution for all the features of a cms.
For now, it is not my top priority and it would take much more than a few beers to make it my top priority. There are too many other things to work on that add more immediate value for more people using mojoPortal. If I stay focused on the things that add the most value, then who knows someone else may do some of the heavy lifting and produce other parts of what will eventually be used to solve this in mojoPortal. New open source projects and frameworks come on line everyday and I'm always on the lookout for things that we could use in mojoPortal.
I'm not worried about how to detect mobile devices that is the easy part, though I will say that I will probably never try to optimize it for particular devices, but only to common phone screen sizes used for iphone, Android ,Win7 but not tailored with a different ui for each device, that would be a lot of expensive work. People using ipads have a big enough screen that they should have no trouble using the normal web page view.
While I have certainly noticed that the Common Phone Pecker has become the dominant species in ecosystems everywhere :-D, my observation is they are mostly using Facebook or other "apps" or text messaging and people still use larger screens for the vast majority of real web browsing.
I do understand that this may be a higher priority for you than it is for me. If targeting mobile phones is what your site is all about there are probably better solutions out there than mojoPortal for that need. I do think we will be able to scratch that itch at some point, but it is going to be a while before we do and I do not want to set any expectations that this will happen soon.
Best,
Joe
