You might try asking on the SciPy-user list, I know the developers of  
scikits.timeseries answer a lot of questions there, and if this is the  
case then it'll affect all modes of parallelism (the multiprocessing  
module, for example) and not just IPython's (and I really hope they  
have a solution for parallel processing -- it's not even clear to me  
why a Date object shouldn't be picklable).
