You probably want to write a codec registry function. Something like this:

import codecs

def latscii_search_function(name):
    if name == 'latscii':
        try:
        	import latscii
        except ImportError:
            return None
        else:
            codec = latscii.Codec()
            return (codec.encode, codec.decode, latscii.StreamReader,
                    latscii.StreamWriter)

codecs.register(latscii_search_function)
