For advanced license yes. Thats another $400 or so (which might not be
very much money for big corps but for me and my one server
installation its more..)

Yep, there are some downsides with serial console. But if it works,
i'd rather use a normal ssh client in my terminal together with the
virtual serial port than sitting in a web browser. But i'll guess I'm
going to evaluate the serial port option when I get the box, and if it
isnt working to good i'll just have to throw up the money and get the
advanced license (even if i'd rather use that money on more "fun"

I've got a supermicro ipmi card now and.. I'm afraid I cannot describe
it with better words than "crappy toy".. Constant IPMI card restarts/
crashes, the serial consol java browser applet stopping responding,
firmware upgrades that b0rks the card totally etc...
