Charles, ".dat" is a hopefully oversubscribed file extension, and the .dat which PyMOL currently recognizes is for Macromodel. If you are have some development skills, consider writing a Python-based CSD file parser for the Chemical Python portion of PyMOL. Any ChemPy model can be loaded straight into PyMOL. This approach doesn't have quite the performance as native C reads but, it will suffice for moderate-throughput applications.
Example Python code for reading MOL files can be found in modules/chempy/mol.py. The code is just over 105 lines and supports both reads and writes. One should be able to add a CSD reader with just an hour or two starting with a description of the CSD file format. Just focus on the atom symbols, coordinates, bonds, and bond orders...the rest can be dealt with later on. I propose using the extension ".csd" for csd structure files.
