TLDR: [1]thekraken@krakenrf.com is looking to pay developers to write
   drivers and such for their open source synchronised 5-radio rtl-sdr,
   which surpassed its funding goal by around 400%.
   The nice thing about doing that is you get to have the community
   drivers match your design preferences, because you wrote them.  I have
   interest but worry I wouldn't likely be able to finish it.
