How can I make two domains use the same data?

In my question on Adapt display size to small devices I already asked for this, but got a different solution, so I ask again with a different wording: In order to make a mobile version of my wiki, I'd like to get two different domains using the same data. I'm sure this should be somehow technically possible, but the question is how.

All the Webs and Topics would be identical, only the domain and the used layout would be different.

redwiki.com/Main/WebHome
redwiki.com/System/blabla
redwiki.com/Private/something
is equal to:
greenwiki.com/Main/WebHome
greenwiki.com/System/blabla
greenwiki.com/Private/something

Maybe I need to set up an entirely new wiki (called greenwiki in my example), but at some place I'd have to mention in configure where the data is stored (in {DataDir}). I guess this may even be possible, so then is the question how I would make a difference in the layout settings of the WebPreferences, because these are stored in the "data" directory, which would be copied on both "wikis" (being the same source).

So my real question is how to generated a domain-dependant WebPreferences section, like writing:

   * #Set SKIN= %IF{'domain'='redwiki.com' then "red" else "green"}%

I suspect that you could do this using a single installation combined with some apache redirects. Essentially, you would configure the mobile domain to "mirror" the regular domain and add the mobile domain name to the {PermittedRedirectHostUrls} in configure. Then add some apache redirects to identify mobile devises and redirect them to the mobile domain. Here's some info on how to do that: Apache2: How To Redirect Users To Mobile Or Normal Web Site Based On Device Using mod_rewrite. Finally, you would set the skin variable as you described. I think this should work.
