I give up, for now. Very promising, but not that easy as you claim. Would be nice with one smooth and easy server for both Rails and PHP. But now I can't get php to work either. When trying the phpinfo it doesn't get the page. It did before, but not after I reinstalled lsws.
To bad, but I need to get back to work with Rails+Apache+Mongrel. If you update the documentation I might have a look at it again. I think you would benefit to get help from a consultant in design and communications.
