Managing abstractions inside M4L devices - "newobj myAbstraction: no such object"

Hello,
Is including an abstraction in the Max "File Preferences" the only way for a M4L device to find this abstraction?

I am sharing with several performers a Live project with M4L devices that use several of my abstractions.
Right now the simplest set of instructions to the performers is:
1/ download myAbstractions folder
2/ download Max
3/ open Max and under Options/File Preferences, include myAbstraction folder in the File Preferences
4/ download Ableton Live
5/ open Live and under Preferences/File Folder/ Max Application click on "browse" and select the application Max you just installed
6/ download my Ableton Live project

Isn't there a more simple way?
I have tried to include the abstractions in the same folder as the .als file but Max still doesn't find the abstractions.
It would be great if there was a sort of "Collect All and Save" for abstractions and externals, wouldn't it?
Or if Max could look into the Live project by default.
I hope I am missing something!

if you have suggestions, please share them! thanks
Florent
