The condor jobmanager deals quite poorly with whitespace in arguments, in 
a way that I cannot see how to work around. (I've run into a very similar 
problem when looking at making Swift run without any shared filesystem).

This bit almost definitely doesn't work with existing jobmanager-condor.

GRAM provided an update package to VDT/OSG the other day that changes 
condor jobmanager whitespace handling so that it may be possible to make 
it work. See this thread: 
http://lists.globus.org/pipermail/gram-user/2009-January/000790.html

With the present deployed infrastructure, one approach might be to have 
the bootstrap script staged in as a file using file transfer mechanisms 
(in the quickest hack case, staged in at the same time as wrapper.sh and 
seq.sh by swift, though this will not work if you are trying to use the 
coaster filesystem provider), allowing the shell command to have spaces 
removed.
