To put this back in the context of comparison to other free virtual host
servers, you can run the console client (windows app) to connect to as
many ESXi servers as you want, but on a one to one basis. That is, open
a new instance of the client for each connection, and within those you
can open consoles to as many VM guests as you want (although once the
network is up I usually prefer to use vnc or NX/freenx directly to the
guest). The licensed vCenter stuff refers to a single app that is
simultaneously aware of all of your ESXi servers and their guests and
can move/fail resources across servers - concepts that I don't think the
other hypervisors even have.
I don't think there is an overall restriction on how many of the free
ESXi servers you install - you just have to treat them as standalone
instances.
