A newer version for WP3.0 is in the works. I would have loved to release it on time for the release of 3.0 but I’m having my finals at the moment so it will have to wait until June 2010. Will include single sign-on as well.
This plugin is for WordPress MU
This plugin basically allows you to host blogs on multiple domain names while maintaining one main site.
For example, the main site could be example.com but users will also be able to sign up for blogs on example.net, example.org or any other domain name that you choose to add.
<ul>
<li>All the sites will have the same settings</li>
<li>No extra blogs/tables are created for the additional domain names</li>
<li>All blogs will be viewable on the Site Admin blog list</li>
</ul>

This plugin allows you to make multiple front end websites from just a single, simple installation of WordPress.
Suppose you have a WordPress site example.com. It contains 100 posts. You want to show some of them on cars.example.com, some on my-super-domain.com and some posts on mobiles.example.com. See? you can show content across multiple subdomains and even on separate domains.
How to do it? Very simple. To setup a new subdomain for example cars.example.com, do the following:
<ul>
<li>
First point cars.example.com to your main website server. This may require changing of DNS records. On many hosting providers this process is called create a “Domain Alias”. The target is that if you browse your new domain or subdomain, it should show the content as you see on your main site.
</li>
<li>
Create a new ‘Contributor’ type user.
</li>
<li>
Put https://cars.example.com in site url field and save.
</li>
<li>
Now, go in Posts and set that author to those posts which you want to show on cars.example.com.
</li>
<li>
That’s all. Now browse https://cars.example.com and you will see posts made by the contributor user of this site.
</li>
</ul>
