For the record, Emacs 22 has that feature:

    *** Processes now have an associated property list where programs
    can maintain process state and other per-process related
    information.

    Use the new functions `process-get' and `process-put' to access,
    add, and modify elements on this property list. Use the new
    functions `process-plist' and `set-process-plist' to access and
    replace the entire property list of a process.
