Pages: Needs slug allow pages outside blog URI

Just recently I upgraded to WordPress 1.3a5.
I’ve been very eager to try out the new “Pages” feature, and in its current state, it looks very promising.
However, I have two wishes for the feature.
First of all, and this has been mentioned here before: Pages need a “post-slug” just like regular posts.
Secondly, and this might very well be impossible, but I’d love it if it was possible to have pages reside outside the blog URI. That is, currently, all pages are currently sub pages of the main page, the main page being defined as the one residing at the blog URI entered in the options.
In my case, my blog is located at /journal/, but I’d want, for instance, my colophon to be located at /colophon/, and not /journal/colophon/.
Doable?
