google "how to make a telepathy plugin for maemo"

one statement from 2014
interesting statement on maemo / meego
"For Maemo and Meego we can add new telepathy plugin with own configuration module in settings."

it appears on initial cursory searching that compared to other platforms
creating telepathy plugins is not only doable, but far less painful than on other platforms...

hunting down methods is the next step.

interesting paper on maemo telepathy and social networks here...

it appears that you should expect a learning curve, not a steep or insurmountable one, but a need to study to achieve your objective .

(some times it is great to learn and know how stuff works, especially to do something new and innovative
...and sometimes it becomes a headache...
personally I enjoy learning new ways to bork a nxx0
...but as well...I enjoy not knowing things ...it adds to the aura of maemo magic ... It is fun sometimes looking at the wizardry in our devices and just realizing that THAT "thing" , "topic", "area" of inspection or research" (whatever it may be... inside our devices ) is so specialized ...I just don't have enough time on the planet in my lifetime to figure out everything in my device...and so I putter away at what little corner of the totality of our devices I decided I do have time to understand ...and so primitively call it "My magic box the gods dropped at my cave entrance" ...)

(actually not to topic divert too much...but I am in perpetual awe at what new thing someone has come up with to implement on the old n8x0's .....or the n900 or n9...even...I mean...really....one guy comes up with a sonar app for the n900...a sonar app!! Another makes a program so once an n900 is hooked up to a drone it then can hack foreign drones in flight, take them over and turn them into slave - zombie - drones under your control!!! My wonder at our devices capabilities never ends....)
