Hi handaxe,

thanks for the hints. I guess, the current owncloud gui problems could be fixed (but I am no gui expert, so I will not do this).

simple_oc is a wrapper to owncloudcmd from mirall. The online-help of owncloudcmd sais that you can specify a config dir, but the source code reveals that this option is parsed but never used. So owncloudcmd seems not completely finished by upstream.

However, there are two config files loaded, one from mirall
and one from ocsync (couldn't find out where it usually resides).

The one from mirall may be used to specify ca certificates and a proxy (btw.: possible solution to your cert questioning problem). The one from ocsync to specify connection timeout etc. My guess is that you can copy these files and owncloudcmd will gather the respective information (e.g. the username of a certain host). Then, some configuration could be shared between both clients.
