I have often thought back to how great UML was. I had filed it under "distant history" when I thought about it last week... Back in 2003 or 2004, I threw together a "virtual hosting" platform using UML. It had a web form accepting payment, and a few minutes later you'd have a fully running virtual machine. I put this together in a couple weeks leading up to PyCon, where we launched it. But we didn't really have the business savvy to take it anywhere, we never had more than a few hundred VMs. We eventually moved to other technologies: VMWare, Xen, Proxmox (KVM). But UML was my favorite. (Xen was my least favorite :-)
