rsync client for Chrome OS?

[Uxio Prego]

Hi, hey android allows execution of _legacy_ static
binary programs, via unpacking of binary as asset,
then chmod ing it properly and finally running it
through a system call [from e.g. the Java userland
of a vanilla android application package].

I doubt that Chrome OS doesn't include some
equivalent facility!

Cheers,
