    FWIW - some time ago (Sept.99) I addressed this issue with Real. I sent them
    a similar bit of info:
     >$ GET http://realg2.example.com:8080/ramgen/foo.rm

    I got this reply:

    I don't have any idea what version they're up to currently or if any of
    this indeed works...
    I lost interest myself.
