For what it is worth, I made a test server/client according to Kay's idea.

+1 for using pvAccess.
Not only would that remove the need for a mailbox waveform record on an IOC somewhere, ..
For what it's worth, you might not need a mailbox IOC.
You can use python + pcaspy as the 'server', and then python + PyEpics or Jython in the CS-Studio display as the client.
So the pickled data goes via Channel Access byte waveform from python server to python/jython client without an intermediate mailbox IOC.
