[FreeNX-kNX] virtualbox, sdl, rdp, freenx, xen

[Alastair Johnson]

You could do that, but unless you're only running a few clients it'll be much 
more resource hungry than the terminal server, and probably won't save you 
much on licensing.

The terminal server has a single Windows instance with a relatively small 
resource increase for each client. Each virtualised Windows is a full Windows 
install so it needs the resources (disk, memory, CPU etc.) to support that. 
It doesn't matter if you're using VirtualBox, VMware, QEmu, Xen since they're 
all just providing a virtual machine. So the virtualised route probably needs 
more hardware resource to run on.

I'm no expert, but you probably need a Windows license for each VM too, at 
about the same cost as your client access license for the terminal server. So 
you might save yourself the cost of Win 2k3. I'll leave you to work out the 
costs for your installation, but I don't think it'll save you much if 
anything.

Now if you can get the apps to run under Wine, or find an equivalent to run on 
linux...
