Ya servage is excellent. You can host multiple domains. You get extra space if you enter a special url with a coupon code...

The thing about servage is that they use CLUSTERS of linux servers. So if one hardware peice goes down, your website is still up on several other servers and your website stays up and running no matter what. Very cool stuff.. never seen anything like it.
