Just in case you all didn't catch the announcement of this fling http://labs.vmware.com/flings/vco-cli I figured I would put the word out. I just played around with it for a bit and it is most useful in my 5.1 environment. I'm not sure if the debugger in 5.5 will trump it or not but I suspect they are complimentary. I am just now spinning up a 5.5 vCO environment and I haven't had a chance to play with the debugger. This is great since it gives you a interactive command shell you can have up and running anytime. Good job to the team that put this together!
