I'm not an expert in SGE, so perhaps someone else can verify my
response, but AFAIK there is no way to submit to a remote SGE server via
DRMAA without having a local SGE installation to reference.  You *might*
be able to get away with just copying into the VM and some
parts of the SGE config which define where the qmaster is, but I don't
know what parts you'd need.

I'd suggest asking in the SGE community if you'd like a definite answer
since it's not a Galaxy-specific issue.
