You could try the Subdomain module (http://drupal.org/project/subdomain) though I think that, in a case like this, you're going to have to be able to modify DNS or configuration files no matter what you do.

Hi,
Is it possible to achieve this with drupal. Something like this http://www.mywedding.com/free-wedding-websites
I have looked at http://drupal.org/node/993166 , but using aegier will require a dedicated server. I need something smaller.
