Hi!
First of all thanks for posting the links! Always nice to get examples for our tech being combined with other libraries and frameworks.
This would be even more useful to others if you could find the time to package this into a git repository with a working Crossbar.io config + minimal notes on the dependencies. I'd then add a link to it from both the Crossbar.io and the Autobahn|Python docs.
Regarding the issue you opened: This really contained at least two issues, so should have been filed as two. Otherwise: Thanks for filing this! There is no set format for issues - anything which gives a defined issue/suggestion is OK, and welcome.
Overall: Welcome to the world of contributing to open source! Hope you continue, and come back with questions any time!
Regards,
Alex
