All right, I got FastCGI and RoR installed...

Questions:

Should Rails apps really live in /home/user/ and not /home/user/public_html?

In the main server configuration I have:
<IfModule mod_fastcgi.c>
FastCgiIpcDir /tmp/fcgi_ipc/
AddHandler fastcgi-script .fcgi
</IfModule>

Do I need to have <Directory> sections in the <VirtualHost> section for each Rails app?

The Agile book talks about a different configuration for FastCGI, but can that <IfModule> section be used within, say, my <Directory> tags in httpd.conf, or in an .htaccess file?

What else do I need to do to get this to work?
