I've being an choice to install VMWare server, however i prefer some thing specific. anybody have ideas?

Are you currently running Home windows? Home windows includes a built-in loopback network adapter that you could install and manage from inside your network configurations. You could have multiple cases of them plus they work/manage as being a physical network adapter.
