[AccessD] Virtual Server and FTP Server

I want to set up an FTP Server on my server at my office.  One option is to
set up a virtual machine under Windows 2003 and then set up the FTP server
on that virtual machine.  In fact my motherboard has two NICs on it and can
thus have two IP addresses, so I could assign one of the NICs to that
virtual machine and the other to the real base OS / machine.  Setting up the
FTP site on a virtual machine helps to isolate security issues to that
virtual machine since the FTP server would no longer be running on my main
server / OS.
 
Does anyone have any experience running Virtual Server 2005?  A download is
available.  Is this a permanent license or is it time limited, and if so
what is the term / cost to license.  Is it possible (using WFW) to publish a
share on the virtual server so that other machines on my network can drop
files onto the share but still limit the virtual machine's access to the
other machines on my network?  Is this a workable / useful idea?
 
Any thoughts in general about this idea?
