yes this is in principle possible ... "only" problem is to write the position data in an valid obj syntax to a file.
have you ever tried to open a obj file in a texteditor? is it plain text? how does the syntax look like? etc.
or is there any kind of scripting language for maya? if so, you could try to generate a maya script with the help of processing, which holds all the position information and copy it via clipboard to maya. might be easier, then to get into the obj syntax.
I have started to work with processing recently and I have been trying to find codes to export lines or curves to a obj file. In the example above I would like to export the agent points as curves to work with it in another programme like maya.
