So after being told on IRC that you can use (i)python and proteus to poke around a running tryton instance(thanks for that hint btw) I tried it and had some "fun" right away:
from proteus import config,Model pcfg = config.set_trytond(database='trytond', config_file='/etc/tryon/trytond.conf')
gave me this:
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)

31 ep, = pkg_resources.iter_entry_points(
---> 32 'trytond.backend', db_type)
33 except ValueError:
ValueError: not enough values to unpack (expected 1, got 0)
During handling of the above exception, another exception occurred:

Took me a while to figure out I just had a typon in the config file path. Since that cost me some time I thought I'd put it on here so that maybe someone else who makes the same mistake doesn't waste as much time on it as me ;) -- and thanks to the always helpful people on IRC #tryton@freenode
