The following function could be useful here - I got it from Dive Into Python
- http://diveintopython.org/scripts_and_streams/index.html#kgp.openanything

It tries to open a file with urllib, and if that fails it uses open():

def openAnything(source):
    # try to open with urllib (if source is http, ftp, or file URL)

    import urllib
    try:
        return urllib.urlopen
(source)
    except (IOError, OSError):
        pass


# try to open with native open function (if source is pathname)
    try:
        return open(source)

    except (IOError, OSError):
        pass


# treat source as string
    import StringIO
    return StringIO.StringIO(str(source))
