apache virtual hosts and SEO, need input

[fris]

How would creating apache virtual hosts on the fly effect if any SEO

basically i can add directories:

/home/sites/domain1.com
/home/sites/domain2.com

etc

and it will work automatically www.domain1.com domain1.com, without adding an apache entry for each domain.

VirtualHost 206.4.112.13>
  UseCanonicalName Off
  ServerAlias www.*
  DocumentRoot /home/sites/
  VirtualDocumentRoot /home/sites/%2+

  <Directory "">
    Options ALL -Indexes
    AllowOverride ALL
  </Directory>

</VirtualHost>

<VirtualHost 206.4.112.13>
  UseCanonicalName Off
  ServerAlias *
  DocumentRoot /home/sites/
  VirtualDocumentRoot /home/sites/%0

  <Directory "">
    Options ALL -Indexes
    AllowOverride ALL
  </Directory>

</VirtualHost>

Question is will it have any effect vs each entry for each domain.

It shouldn't have any effect should it? Except for the ip numbers being the same.
