    I have a proposal into Reftek to develop an operator console for
    command & control of digitizers via RTPD.  If it is accepted, then
    that would do what you want.  Alternatively, I could develop a custom
    application which monitors state of health.  I am already working on
    something similar for Ken Smith.  This program broadcasts status
    requests once per minute and then takes the replies and builds a
    digitizer voltage stream for each station which is written to an ORB.

    I wrote a standalone SAC to mini-seed program for Utah a while back.  It would
    be a fairly straightforward process to modify this to yank its data from a
    wavserver instead of a disk file.

    If you would be interested in contracting for either of these programs then
    please let me know and we can discuss things in more detail.
