Add an additional discovery mechanism: IPv6 LAN discovery (ping6 -c4 -I eth0 ff02::1)

Support use of local IPv6 address and sync with remote IPv6 server. Check data structures and library calls.

Implement two connection modes. One permanent (connect - sync - wait -sync - ... ) and one transient (connect - sync - disconnect). Update the protocol with new commands for...

Parallelize the synchronization process (spawn multiple clients to sync with different data bases). An impl. would probably use a small thread pool (2-10 threads). Note: Must document thread safety constraints...

Today all data is abandoned if a transaction is interrupted. Don't do that. Make the transaction more robust and save all valid data.

Encrypt the sender identity in messages that have a receiver. Currently, only the message text is encrypted.
