Well, I did say it was a wild idea... But on the other hand, I haven't heard any better suggestions. And the only problems are: 1. Not all OSes support raw disk access or seekable mag tape. 2. A small LIF transfer utility will have to be written for each OS.

No, you definitely have a point. But yes, if people plan to write a separate application to access this device, then you worry about system caching of data does not apply. But I still do not think that writing such a program for every platform (or even a noticeable number of them) is going to happen.

Right. Now, do people want to transfer some information, or are we going to continue this mad idea all night?
