Well, looking at the spec that was linked earlier in this thread... When someone is using a TPV that can do OTR (and the user has indicated a willingness to use it), then many(all?) their chats will have " " at the end (this is <sp><tab><sp><sp><tab><tab><tab><tab><sp><tab><sp><tab><sp><tab><sp><sp><sp><sp><tab><tab><sp><sp><tab><sp>). I'm guessing that it is thought that no one would notice these unless they were looking for them.
If someone wants to begin encryption with someone they think can handle OTR (is this "coming out of the closet?") then they send "?OTR?v2?" as a chat. I'm guessing that if a TPV doesn't see those spaces or doesn't get the response it expects from its query, that it figures out the other person doesn't support OTR?
