The program is from Lattice (the same people who do Lattice C,
Sidetalk etc.  I would agree with the comments above, the only
problem is a loss of speed in reading stuff off it since it is
encrypted.  I have also come across some Syquest 5Mb (removable
hard disk) units where they implement encryption (be warned that
it's very slow tho') so that might be an alternative.
