[LAD] Saving plugin presets

Hi, i would like to know if somebody has already thought about a (unified) way to save or export the settings of ladspa plugins (or vst,lv2..) I'm familiar with the idea of LASH, but i want to share plugin settings between different sessions. A typical use case: After recording songs with my drumset, the gate-plugin applied to basedrum and snare has most times (nearly) the same setting. At the moment this is a quite painful task: Ardour is able to save the settings, but you can't export these or exchange them between other applications. In addition, ardour's ladspa plugin dialog can just save the settings, changing an already saved settings is not possible. This results in a heap of saved settings and old revisions.. It would be great to export these settings, it could be implemented as a feature in applications like ardour2 ,jackrack or hydrogen. After exporting the setting to a plain text file (or xml), sharing the file with other people or between your computer would be no problem. What are your thoughts on this? What are the disadvantages? Thanks, Sebastian
