VMware 3.x has NAT networks too, and it has the benefit of being GA software 
:-)

Host-only networks don't allow the OS in the virtual machine (aka "guest") to 
communicate with the world outside the hosting Linux machine.  If you choose 
your network adresses carefully and can control routing sufficiently, you can 
get past this problem.  NAT networks work exactly like they do anywhere else, 
like at home with a cable modem and a NATing firewall - the guest OS vanishes 
behind the NAT "box".

In other words, VMware acts like an Ethernet bridge, passing packets between 
the outside and bridged networks transparently.
