And i wish there were a real free-for-home-use version. yes yes i know about the stripped license you can run at home, and vmug.
Both have limitations.
Compare to citrix, proxmox or nutanix all have community editions with little or no limitations.
Think about MS from the win 9x - windows xp days, everyone had a key that floated around and were able to load it at home without to much trouble. While not technically free, its effectively the same thing. It part of why windows blew up. go look at Beos form the same time frame, or amiga, both i think were technically superior.
