Is your viewer going to be publicly available, and if so, might you
tell us more about it?
The RO package* includes a DS9 module that uses xpa to do its thing.
You could easily adapt it for use with other xpa apps. However, it's
not as fast as it might be -- it calls the command-line xpa commands
rather than linking to the C API.
I also have a SWIG interface for xpa from a colleague; I have sent
him email to ask him how publicly available it is and will let you
*available from <http://www.astro.washington.edu/rowen/ROPython.html>.
