Cool thanks for that. I made a quick rewrite of the server using flask. I haven't touched or even checked the client part at all...
If you want to have a look, it s there : https://github.com/asmodehn/rostful/tree/flask
I am still modifying it and testing everything, for the server part.
To be honest I don't know enough of rostful (or even flask) yet to be able to decide on a nice code design, so I ll do that later. So it s not really clean yet.
But anyway, if you have any feedback, let me know !
