I should have a look at the differences to MicroPython.

MicroPython ... sounds interesting.

MicroPython ... sounds interesting.

In the microcontroller universe, MicroPython often is fast enough and
with such an interactive language you can avoid fat SDKs on PCNannys and
compiling, flashing the µC and such. Lisp. Lua and some other languages
can do that too, but knowledge about Python is more wide spread. So
within a few limits you can run the same code on Nixens and on
microcontrollers.

You're welcome! I developed yesterday another solution, which I call o2o
(Onion2Onion), which allows Alice and Bob very easily to set-up Tor Hidden
Services, a client and server Go program, to exchange data from PC to PC
directly, without using third party servers. Like in the old days when
people exchanged data with 300 baud acoustic modems, via telephone copper
lines. :-) Thus no need for Remailer Messages, Nyms, Bitmessage, pastebins etc.
This works bidirectional and not like IIRC OnionShare, in one direktion.

A sample client session:

C:\Users\xxxxxx\Desktop>client 127.0.0.1:5870 bin secretPassword
Uploading... 100.00%
Server response: File bin successfully uploaded

File uploaded successfully

C:\Users\xxxxxx\Desktop>client -u "Stefan Claas" 127.0.0.1:5870 msg.txt secretPassword
Uploading... 100.00%
Server response: File msg.txt successfully uploaded

File uploaded successfully

Server output:

Server is running on http://localhost:8080
File received: bin at 17:52:10 by Anonymous
File received: msg.txt at 17:52:30 by Stefan Claas

I must prepare a README and once done I fire it up to GitHub.

Updated nekoweb with a -T parameter for Tor usage.
