Great, thanks for the info.  One quick question, in the diff I see
this towards the end:

-The PBS mode uses the Portable Batch System [PBS]_ to start the engines.  To us
e this mode, you first need to create a PBS script template that will be used to
 start the engines.  Here is a sample PBS script template:
+The PBS mode uses the Portable Batch System [PBS]_ to start the engines.

-.. sourcecode:: bash
+To start an ipcluster using the Portable Batch System::
+
+    $ ipcluster pbs -n 12

-    #PBS -N ipython
-    #PBS -j oe
-    #PBS -l walltime=00:10:00
-    #PBS -l nodes=${n/4}:ppn=4
-    #PBS -q parallel
+The above command will launch a PBS job array with 12 tasks using the default q
ueue. If you would like to submit the job to a different queue use the -q option
:

-    cd $$PBS_O_WORKDIR
-    export PATH=$$HOME/usr/local/bin
-    export PYTHONPATH=$$HOME/usr/local/lib/python2.4/site-packages
-    /usr/local/bin/mpiexec -n ${n} ipengine --logfile=$$PBS_O_WORKDIR/ipengine
+    $ ipcluster pbs -n 12 -q hpcqueue


Is it correct to remove all references to the #PBS lines?  Do  your
improvements to PBS obsolete completely the need for the manual script
writing we had before?

I just want to make sure that I understand that correctly before I
merge it, once we clarify this I'll merge and will cut an RC so we can
get it tested.

Cheers,

f
