On my systems, i'm using PCMCIA with Cnet.device and MiamiDX. I have set up a FTP on my pc wich functions as a fileserver and my Miggys get what they need from there. I'm renting out presentation systems which is also configured to log onto my FTP to get script updates. All this works well, but this is allways small files (Max 200kb/file) If i want to backup one of my Amiga partitions, i pack them to a .lha file and move them over to the FTP. If this is a large partition/file, the systems sometimes hangs, but if i retry, it will work after a while. I think as has been mentioned, the system can't handle the immense load over time, but i have a lot more positive experience with pcmcia than serial/paralell cable.
