[PD] Two Pd instances with different startup options

[Jean-Marie Adrien]

Hello
I try to run two different pd instances with different startup options on Mac Os 10.7. 

Is there a way to setup the audio / midi devices and so on from within a patch ? something like the declare object ?
Or run from terminal with two different command lines (but i will have then to script the terminal application, which i never done !)
Or rename one of the pd applications to fool the MAC ?
Thanks
