RE: Linking to alternate resources

I agree with you that <link rel="alternate" media="handheld"> in theory should be used by a desktop page to say "hey, there is a mobile optimized version of me", however now it is also used to say "hey myself it is a mobile web page!" (if the href atribute points to the page itself).

AFAIK Opera Mini uses other mechanism which is the detection of a <link rel="stylesheet" type="text/css" media="handheld">. If they see that they won't touch your page. That's because in MyMobileWeb we send a fake CSS to flag Opera Mini our pages :)

I agree that something standard is needed, to say that a page is a mobile optimized page, but also to say, for which DCs a page provide the best user experience.

I wonder if POWDER has something to do with this and can provide another solution ...

And implementations not exactly thick on the ground.

I'm not sure how this helps? I am looking for a way for a content provider to say "This representation is intended for mobile". Media queries doesn't do that, does it. Some think like:

<meta name="media" content="handheld" />

would fit the bill.
