Clusterfuck.
OpenVMS is one freaky system. And I mean - FREAKY. It feels like MS-DOS on speed, and yet it supports clustering better than the average operating system supports networking. I can find my way home from any random unix you drop me in, but it took me fifteen minutes to figure out how to copy a file. I'm not kidding here.
This beta site is hosted on a public OpenVMS cluster - Deathrow - and yes, you can get your own account there. Thanks ivy/cvisors for pointing that out! Always eager to screw around in a new environment, heh.
