[[http://www.jlab.org/hpc/JPARSS/][JPARSS]] is the Java Parallel Secure Stream (Socket), a package designed to achieve optimal TCP performance in a grid environment using partitioned data and parallel Java streams. It enables single sign-on, certificate delegation and secure or plain-text data/file transfer using several security components based on X.509 certificate and SSL.

As the source code for JPARSS is available and it does not require a Globus installation, this could provide a suitable protocol for large data transfers.

On the client side, JPARSS provides two parallel file transfer client APIs: one for peer-to-peer transfer and one for 3rd party transfer.
I've tested the peer-to-peer transfer using an NVO proxy certificate.
