I very much doubt that Chrome OS would make this possible, given its
focus on security.  (If it _were_ possible to exec a user-supplied
file in normal mode, one could do all sorts of interesting things
with executable shell scripts -- like setting DISPLAY to point to
some other machine.)

While it would certainly be possible to import a blob that happened
to be a binary for some CPU type (into, say, the Downloads directory),
without developer mode there is no chmod command and thus no way to
mark that binary as executable.  Also, I suspect that user-accessible
filesystems are mounted no-exec.

I suspect what I'm looking for is a reimplementation of rsync (or a
useful subset, e.g. I doubt I need ACL support) in Java.
