sure you can get the name of the calling function. its printed when a 
exception is thrown, isn't it? ;-)

so one way is so a "try: raise except: ..." and then inspect the traceback 
using the module of the same name.
however i think i saw more elegant soltions a while ago in a thread. maybe 
a search on groups.google.com brings them up.
