Glad to have you around again!

I'm still in India and will be offline as of tomorrow (traveling
back)...   But I'd suggest you have at least a look at:

http://nipy.sourceforge.net/nipype/

Nipype is Satra's brainchild (the same Satra who has committed the
recent work on ipython) and it already has support for IPython's
parallel execution using the 0.10.x code.  It was also the motivation
behind some of the new DAG support, as we hope in the future to have
even better integration between nipype and ipython.

Satra is also in India right now (we were at the same conference) but
he's on holiday for a fe days with his family and likely offline, so I
expect him to pitch in only a little bit later.  But I hope that in a
few days when people's travel schedules normalize, we can see what can
be done to benefit from common goals so that we reuse as much of the
effort and manpower as possible.

All the best,

f
