That's fine - all I really wanted was to know if it's possible, and a nudge in the right direction -- thanks!

Yes indeed, although I only used the VirtualHost example as it's the most often-used. Unless I'm much mistaken, mod_vhost_dbd only allows you to set the document root, and all other mass virtualhosting solutions that I've seen are quite limited -- nowhere near this flexible. Say you wanted to add some redirects to your virtual hosts too, after the directories have been rearranged, for example... as far as I know, no module allows you to do anything like this: <SQLRepeat "SELECT baz, bar, qux FROM sometable WHERE baz='foo'"> <VirtualHost *:80> DocumentRoot /www/root/path/$baz ServerName $bar ServerAdmin $qux <SQLRepeat "SELECT was, now FROM redirects WHERE type='permanent' AND servername = ?" $bar> RedirectPermanent "$was" "$now" </SQLRepeat> </VirtualHost> </SQLRepeat> If you're interested, I've posted a bit more about it on my blog while I'm still fleshing out the idea: http://www.dmi.me.uk/blog/2008/08/13/modules-for-apache-and-php/ I've been looking at mod_macro for inspiration and to see how it does the substitution/re-parsing, and I think I may end up borrowing a few chunks of its code to avoid re-inventing the wheel...
