it's an educational experience

In the quest to build mysoundproperty.com, I've been working on tying up all the loose ends left over from our installation prior to moving over to Ruby-on-Rails. One of the things I've been kicking around is...should i use some nifty .htaccess redirects to map subdomains to individual controllers. This would mean my current urls that look like http://mysoundproperty.com/app/email_dean would turn into http://app.mysoundproperty/email_dean (which doesn't work). Dean Orrico's blog would become http://blog.mysoundproperty/dean instead of http://mysoundproperty.com/blog/dean. I like this just from more an aesthetic viewpoint, but i think in rails management of the subdomains isn't exactly straightforward.
