[Telepathy] Encryption and OTR

[Reşat SABIQ]

Hi,

I would appreciate any clarifications with regards to encrypted 
communication, in particular when using gtalk.
Specifically, here it says
A. OTR is currently not supported:
http://live.gnome.org/Empathy/FAQ#Will_Empathy_have_OTR_.28.22Off_The_Record.22.29_support.3F
But at the same time, for gtalk, there is a checkbox under account 
setting, Advanced:
Encryption required (TLS/SSL)

The latter suggests to me that
B. when Encryption required (TLS/SSL) checkbox is selected, gtalk 
correspondence will be encrypted.

Are both statements, A. and B., true? If so, what extra benefit will 
future support for A. bring? If B. is true, it appears that it would 
just eliminate logging when in OTR, but that can't be it, because that 
can be done w/o protocol modifications.

Thanks.
