Yes. The most recent "prerelease" versions of Jemplode (found at www.jempeg.org
) can connect to the HSX-109 and send files to it, just like Emplode does. It is essentially a Java version of Emplode. It only works over ethernet and HPNA, not USB, though.
Mike and I are currently trying to figure out why it's slower sending files from Jemplode than it is from Emplode, but at least it works at the moment.
Jemplode is a very neat little program, check it out.
