[Inkscape-user] open file into existing instance from terminal?

Hi,

is there a way to send an existing inkscape instance a file-open message (with the document name as argument) from a terminal or another process?

It seems, the dbus interface would be the way to go but the API documentation only mentions a command to open a new document (which works BTW).

I'm on linux and inkscape is bzr-inkscape 0.91
