[OTR-dev] Fwd: EMPP - What can XMPP benefit from the new Echo Chat Protocol?

[Randolph D.]

Dear Nathan
thanks for the update, i am not advanced with OTR. I just try to understand
both, how the encryption of GoldBug works and how ORT is sending it. One
Point was, that you send your message always to ONE Server, e.g. Jabber /
XMPP Server.
With a Echo Server from GoldBug E*MPP you send the message to 3-4 Servers
parallel, so the missunderstanding of the question was not to send it in
sequence. I just think with the new EMPP Server model, which sends out
redundancy to 3-4 Servers at the same time. When my friend has my key, and
i send it over a jabber server, this route can be mapped.
When I connect to several jabber Servers, and I would modify OTR to send it
to 4 jabber Servers, would the Destination then get the message several
times? Or just once or would the Connection be dropped, as I have no
Account at the other jabber Servers?
Ok, that was the thought in regard to EMPP and XMPP Comparison.
As I see, OTR is a plugin, now the tought to integrate the echo sever
protocol, then you send our your message either over jabber and as well
over E*MPP and the Destination with the same plugin would be able to get
it, either over echo and/or over jabber.

The thing is: of course you can send the OTR (or as well GoldBug)
encryption over a jabber server.
And of course you can send OTR over GoldBug. In case this is done, you need
no accounts at jabber server anymore. You would be free.

Should we test it? Send me your key
