OGSA-BES had some long discussion about job states, we should look on  
this. JSDL is no option here, since their job is over after the job  
submission.

  I vote for an updated field study, where we compare the available  
job state information in the most prominent DRM systems. The key is  
to find the least common denominator - therefore this would be the  
chance to remove the different SUSPENDED states ;-)
