An eclectic approach for collaborative GnuCash

[Emmanuel Florent]

Once would like a multi-user Gnucash without the SGDB/VPN setup nightmare.
Dream...
The goal is to work on books on multiple computers and with multiple users.
I've a proposal for a Python script that take a Gnucash xml file,
convert it to post request on a REST service.
Then using the same process it can pull down data to merge an xml file
from the nosql db.
To get an idea of the whole thing from a programmer view,
here are the  unit test:

What do you think of this off-topic proposal ?
Would you have achieved the same goal differently ? How ? Why ?
This project will at least totally fail because ... ?

Best regards
