Apache server modification question for MultiSite Domain Mapping

I am interested in setting up a WordPress MultiSite configuration on RackSpace hosting with the Domain Mapping plugin.

After speaking with sales and a few Cloud Server techs, they did some research into it and think they may have the solution to automate the Domain Mapping piece.

Before I test it out, can anyone here with Apache server chops take a look at the VirtualHost code they think will get the httpd.conf file to automatically redirect domains added via the Domain Mapping plugin to the sub-directory of the MultiSite within WordPress?

<VirtualHost *:80>
<Directory /var/www/vhosts/wordpress>
AllowOverride Fileinfo Options
</Directory>
</VirtualHost>

Please advise,

Thanks
