What do you mean by "cross-platform"?

OpenSolaris has an OSS (CDDL'ed) PKCS#11 softtoken provider that does
pretty much what you want.  It stores its files in a filesystem, by
default in a sub-directory of the user's home directory; filesystem type
does not matter.  Since you can put filesystems on a USB flash drive
that should suffice for a "cross-platform" softtoken.

The specifics of the Solaris softtoken's directory layout and file
formats are project private interfaces IIRC, but if there's interest I
imagine that we could document them, make them committed public
interfaces and help establish a standard for a cross-platform softtoken.
