This is not a technical issue. Valid XHTML and CSS mean sites will render fine in all modern browsers.
I've moved this thread to "Suggestions forum", where it is more appropriate.
From what I see of the Mobi-Cart platform it appears to be able to create iphone or android apps for navigation of items for sale, rather than just relying on xhtml pages.
A mobile interface for Kartris using XHTML is something that is on our roadmap for the future but i'll be interested to see how Mobi-Cart works when its released.
