What I am thinking to do is have a random-string generator subroutine, so that the files generated for each user are separated from those of the others. Sound reasonable approach?

It may seem like that now, but don't do this. Sooner or later the generator will repeat one of the random strings and then the trouble begins. Better to use a truly unique identifier (which could be as simple as an incrementing integer).
