[OTR-users] Visible Metadata?

[Robert Pollak]

Hello list,

I am new to OTR messaging, and I have got a question:

Do I understand correctly that the use of OTR messaging does not hide
(e.g. from the NSA or other network sniffers :) the fact that some
encrypted communication has taken place between two visible IP
adresses?

(So far, It have found Bitmessage as the only approach to hide this
metadata, but OTOH there is no forward secrecy with Bitmessage.)
