We have the idea of doing it, but not in a very literal sense
(translating idl routines to Python counterparts). There has been
some work in this area on our part, but because of budget pressures,
much less over the last 2 years than hoped (things are looking better
now, but it may be some months before activity picks up on this front
again).
Work so far on our part has centered on:
Coordinate transformation utilities
Synthetic photometry
So if you are interested in doing more literal translations, please
feel free to go right ahead. There is even a place to put such stuff:
