My approach to this (which isn't pretty :-) would be to interpose a relay
- such as a Jabber server - through which your progeny would connect,
and hack that relay to take over the protocol stream to do a sign-off.
This isn't a trivial problem - there's some reverse engineering to be
pulled off, although all the necessary protocol knowledge is probably
embedded somewhere in Jabber code.

This is form of man-in-the-middle attack, and will look great on your
hacking credentials.
