To answer your question... Yes!  It is really easy to run multiple  
instances of Nagios on the same machine. :-)  A simple approach,  
albeit more overhead, is to simply configure/install both Nagios and  
Nagios Plugins in a different directories by passing the '--prefix=/ 
path/to/separate/nagios/installations'.  Each instance will than have  
its own init script and apache web alias (which you could setup as  
customer1.domain.com).  I think it is a great way to separate  
customers instances, though you may have to do some scalability  
testing to see how far you can push your hardware.

It is not as elegant as Gerhard's method
(http://people.consol.de/~lausser/nagios/more-than-one-nagios.html 
) BUT it has the ability to update each individual instance of Nagios,  
Nagios Plugins, and 'configuration changes' without affecting the  
other instances.  Which I think is really nice.  :-)  As another  
benefit.. you can give each instance owner full rights to their  
instance.

We use it internally to test out different versions and combinations  
of Nagios and Nagios Plugins.


::For Example::

In Nagios source directory:
./configure --with-command-group=nagcmd --prefix=/path/to/separate/ 
nagios/installations
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
htpasswd -c /path/to/separate/nagios/installations/etc/htpasswd.users  
nagiosadmin

In the Nagios Plugins source directory:
./configure --with-nagios-user=nagios --with-nagios-group=nagios -- 
prefix=/path/to/separate/nagios/installations
make
make install


Good luck!
