So are we to assume that there are WU's coming that will have lower virtual memory requirements? The memory hogs are getting tired.

I don't have any advanced knowledge of future Rosetta releases. But my experience with the project tells me they are working on such modications to the program, and so yes, I would assume both that other WUs will require less memory, and that future releases will improve the memory footprint.

It may be helpful if folks would post the WU name and their observations of memory usage. That will provide something concrete to compare against when a new release comes out.
