Use HDF5 --- both Matlab and Python can work with it. On the Python
side use either h5py or PyTables, depending on which one you like more.

As you found out, the .mat file format simply does not support data
bigger than 4 GB. The development version of Scipy (to be 0.13.0)
should throw a warning AFAIK.
