Using an unused VMWare 3 license made obsolete by my V.MWare 4 license, I installed the port on my Thinkpad a20p running FreeBSD 5.1. I had trouble getting the network to work, and read only one guest OS per session is allowed. I plan to use Linux as the host OS for my next test, and I hope to use the same system for the rest of the time as a guest OS. I used an unused license to install the port, started the VMware.sh, and created a /usr/lib/vmware/licenses/user directory with the license.ws.0 file in it.”]
