Netflow Data with nfdump

Hi,
I would like to work with netflow data and I would like to ask if there are already 'work in progress' projects about about this topic. I would like to process nfcapd files and analize them through nfdump in order to produce some statistics. I've already did it converting files to csv format, now I would like to work directly on nfcapd format.
Thank you in advance!
