Pickle for MPI

[tooper]

Hello,

Did anybody tried python pickle module over heterogeneous 32/64 bits
mpi exchanges to overcome the translation problem ? i.e. pickling on
one side (let's say a 32-bits OS side), sending the buffer as string
through mpi and unpickling on the other side (let's say a 64-bits OS
side)


Any well known pitfall or advice before I try this way would be welcome
! 
Thanks a lot in advance ! 
Regards, 
Thierry
