The ssh tunnel will only connect to the machine you're ssh'd into; it
won't work with interactive queues.

To get around this, we'll need to implement a client/server
functionality.  I've been looking at how to do this for things like
volume rendering, so that a reason session can drive a set of render
nodes.  I think for your purposes maybe you could project in advance
and then use reason to view the projection.

Also, why are you taking all_data if you want to project?  It should
be memory conservative for an 800^3 box if you actually *do* project,
by right clicking on the output file in the list of outputs.
