Is it that they have to manipulate the .htaccess file as opposed to letting you + wordpress handle it?
If so, here’s the info for a root install:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
and what wp produces in a subfolder (replace the * areas with your own domain info):
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /*foldername*/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /*foldername*/index.php [L]
</IfModule>
# END WordPress
The other thing is that if you’re using something besides the regular permalinks, that’s going to need changing within wp. So what you can do is select the setup you want and then copy what wp shows in the field at the bottom of the page if your .htaccess isn’t writeable.
