I don't know about this. Matti is probably the best person to answer this one.

you can write hdf5 from matlab or python. Writing the data is easy. It might
be more complicated to store the measurement info structure (or
dictionary in python).
Note that moving away from the fif format will make things difficult to go
all the way to the inverse problem and source estimation.

let me know if you need help with that.
