The way I understand it is that you have to have an entry in virtual hosting for both:
NameVirtualHost 216.27.160.12:80
<VirtualHost 216.27.160.12:80>
ServerName clockwatching.net
ServerAdmin
root@clockwatching.net
ServerAlias clockwatching.net *.clockwatching.net
DocumentRoot /www_main
</VirtualHost>
<VirtualHost 216.27.160.12:80>
ServerName porchsittingpress.com
ServerAdmin
nick@clockwatching.net
ServerAlias porchsittingpress.com *.porchsittingpress.com
DocumentRoot /home/nick/public_html/Porch
CustomLog /var/log/apache/psp_access_log common
ErrorLog /var/log/apache/psp_error_log
</VirtualHost>
