Now that the hardware server will be inside the FPGA for Metis & Hermes, I guess it would be reasonable to have the dspserver multiplatform including OSX (I think it already runs under Windows).
Then Heterodyne can connect to the dspserver.

Could you please give more details about your plugin architecture for Heterodyne? Is it possible to use plugins written in Macruby?
Macruby is fast approaching 1.0 release and from what I read it will be as fast as Objective-C.

These are used in the dttsp portion of the code.  You can find my changes in my SVN repository at:  https://www.xenotropic.com/ham-svn/mac-ghpsdr.

With the plugin architecture that I'm playing with on Heterodyne, I'm also planning on a ghpsdr3 server plugin that will connect the Heterodyne UI to any ghpsdr3 compatible server.  Again, my time is limited to a large extent right now, so don't hold your breath.
