I would go with the vrt standard http://www.digitalif.org/
vrt gives you a standard for digitized if data and context/metadata. 
Also we have a library for it in gnuradio :-)

Given libvrt and pmts in gnuradio, one could implement a 
vrt_file_source/sink and use vrt as an interchange format for "saved" 
digital if data as well as the live-streaming data.

Of course, a lot of development/polishing has to be done before we can 
practically have these capabilities.
