Not familiar with Tcl/Tk programming, so I really don't know if this language
is suitable for communication with the iButtons.

Actually, the optimal solution would be to make a kernel device driver for the
iButtons. Then you could just use whatever tools you like for moving files to
and from the button. But, I'm not capable of such a task at the moment...

Feel free to submit patches to mibfm if you have any ideas. You are also welcome
to use my source as a basis for your own project.

The reason for using the DS9097U-9 which is based on the DS2480 is that
it is, to my knowledge, the only interface supported by the routines from
Dallas Semiconductor.

The DS9097U-9 with a Blue Dot Receptor costs $15 from Dallas Semi., so it's
not *that* expsensive. Besides, you get the very nice receptor which you can
have on your monitor. See http://www.ibutton.com for details. You can also
order iButtons from here. Remember that you would have to pay for shipping and
handling.

Prices from Maplin in the UK:

DS1993 - £  ~5 ($  ~8)
DS1995 - £  ~9 ($ ~15)
DS1996 - £ ~12 ($ ~20)
