None that I've edver found. I have, however, written several applications that "bit-bang" the parallel port to talk to SPI interfaces (this is how many AVR processors are prograamed in-circuit using software like PonyProg). Be aware that this technique requires an additional "kernel-level driver" in the NT-series of Windows products (NT/2000/XP) do to the protected nature of I/O on those operating systems. Windows 3.1/9x/Me do not require this software and you can fiddle with the parallel port pretty easily.
