One thing I'd love to see would be an Azimuth mount controller that worked with Digital Universe from syzygy.
Arexx plug-in - FPGA controller - sounds plausible.
I do not know much about the FPGA side of things, I use an Amiga One rather than a SAM. However, the Arexx feature set in v2.x of Digital Universe should certainly be able to output the data you would need.
It may be some time off though, I am still working on v1.6.
Bill.
