I wasn't aware of the ram_file module (is anyone supposed to be aware of
it, and what is it mainly used for?), but to me, it looks at a first
glance that they have little in common. My module uses no special
driver, and can connect a reader and a writer as a pipe without having
to store the entire file, or create a readable stream from a string;
however, it does not support seeking. Since ram_file is not documented
(not even in the code) it's a bit hard to see what it can and can't do.

By the way, why just a ram_file, and not a full ram-disk file system?
