and first of all, thanks for testing the OFDM codes.

There's no simple way to do this, which I believe is an omission. I've
created http://gnuradio.org/redmine/issues/603 and will add a block
Until then, you'll have to load the block into an array, split that into
manageable chunks and pass all of them as tagged streams to the
vector_source (in Python land).
