I wonder what the erase page size is on microsd cards: it could end up
needing a lot of extra block copies or bigger ram buffers.  FAT32 is
pretty simple though, I thought.  If not, it's possible to implement an
old-fashioned Unix-style file system with a few hundred lines of code.

20k seems way too much for a basic fat fs.  I wonder what's going on.  I
can see usefulness in being able to call C code from Forth, though that
wouldn't seem to require writing the Forth itself in C.  But, there's
an interesting eForth port to C:

The C part is only about 500 LOC.

Again something really seems wrong there, if you mean low exponent RSA
encryption.  Maybe a badly chosen algorithm or something.  Even 170 msec
sounds kind of slow.  If you post the code, I can take a look.
