First test for external editor has been a resounding success!
While using the editor (ADL-ED) it creates files in users/user/adlengine folder.. which if adlengine is open, it will listen for and IF it find them it processes them accordingly.
e.g.
run script.adldata - if adlengine finds this file in the folder, it will read the data, run the script and delete the file.
