I sent the project a note and here's the response:
There are currently no plans for releasing a 64-bit version for Linux, but we'd be glad to have you contribute it to the project if you decide to do so.
I haved used EPF to develop process for BRAC movements in the military and I'm currently using the EPF to develop a Knowledge Management process. I would welcome the opportunity discuss my work via a webinar with the EPF Community. Can someone inform me on how I would convert my applications developed in previous versions of EPF over to the latest version.
