STILTS  and TOPCAT  have excellent cross-matching functionality, provided via the STIL  library.
You can browse the code online .
Unfortunately it's all Java and can only be accessed from Jython, not CPython .
Because all my analysis scripts are CPython I am saving my source lists to FITS files and make an external call to stilts for the cross-matching at the moment.
Having similar functionality in astropy would be great!
