so, you want to find out how many users hosting their site along yours on dreamhost server?
this command will give you the amount of users on the server.
awk -F: ‘$3 > 999 { print $0}’ /etc/passwd | wc -l
each user have at least one site.

I am using luigi.dreamhost.com:
[luigi]$ awk -F: ‘$3 > 999 { print $0}’ /etc/passwd | wc -l
797

there are at least 797 users on luigi and probably a lot more sites.
