I am emailing as an interested party on behalf of some people on the
   cypherpunks email list.   We are considering a project implementing a
   large anonymization network, hopefully in excess of 1000 nodes.  One
   possibility is that the hardware for a node will be a Raspberry Pi 4
   computer, nodes which could be placed in residences.   We hope to get
   subsidies to buy the hardware, and possibly partly-subsidized Internet
   service as well.  We want to amount to competition to the TOR system.
   Can you direct us to literature, or any information that would help us
   planning this project?  I am copying this email to the Cypherpunks
   email list.
