I think I've come up with the basic concepts to develop a theme for our upcoming website so that it can be accessed by smartphones and PDAs (those that use Mobile XHTML browsers with a screen width of at least 240 pixels, that is - I'm not even going to attempt to get a WAP browser to render something as complex as our site, even though I know from experience in coding WAP that it's possible - and a total pain in the ass... :-). (When I'm done with this mobile theme, I might release it to the community, as from what I can see there's only one other mobile theme that's ever been done.)My question is, how do get my site to simultaneously run off multiple themes? I understand how to run multiple sites off one Drupal install; do I treat this as two separate sites accessing the same database? (And wouldn't that cause MySQL file locking problems?) I also know how to use a browser sniffer on our domain index to figure out who's on mobile - but what happens from there? What do I point the different broswers to? Thanks in advance for any help anyone can offer --
