You may not want to spend the money, but Clanto comes with Amiga explorer. You can use a null modem cable to connect your amiga to a PC. There was a way to get the file needed on the amiga side to start the amiga explorer on the amiga end, It's been a long time since I have done that, but it is possible and works very well, and if I remember right, on the PC side you can map the amiga drives as though they are networked. This method is very slow though, no where near the speeds of network.
Good luck
