Using the "session id" is easier for "non computer experts". I have
been thinking how to make it more friendly towards "non computer experts".
Perhaps we could permanently display the session-id somewhere.

Another issue is that no non-expert will even realise to right-click the OTR
button. The alternative via pop-ups though is also not a good way, and
annoys the heck out of the more expert users.

Similar things have been done before, such as bubble-babble.

I'm not sure how that all fits into the fingerprint of the *other*
