If the transfer time was really slow, I could see wanting to return a subset of data without duplication, and then allow the application to query locally among that data for all the various things it needs. That seems so unlikely that I'd think a distributed sqlite database would be a better idea instead, and just have it sync up when it can, and always query local.
