Multiple Hudson instances on one machine

Hi,

We've installed multiple instances of Hudson on a single LINUX server with out problems. We

1) created a new user for each instance of Hudson we required
2) installed a new version of Tomcat and Hudson for each user.

Hudson's home directory is a sub directory of the users home directory, so there were no conflicts  :-)

I couldn't say how you'd do this on a Windows Server.

The only problem we had was when we needed to allocate ports when running unit tests. If two different Hudson instances wanted exclusive access to use the same port at the same time then we got false failures of some of our tests.
