SSB Log Entry 57

Do any #ssb-implementations exist yet that are able to host a full SSB node without the use of NodeJS? That is to say, implement all of the functionality of ssb-server and at least partially implement ssb-client? I see some neat looking Python examples on Github, but they appear to be partial implementations dealing with specific subsystems, such as SHS.

I am curious for the sake of #ssb-learning.
