[Psi-Devel] QT Messenger Join Venture

[Michael Schmidt]

Kevin, thanks for the info,
this was a real interest, heard about jabber serverless, but did not
know, that is is already such elaborated, that clients build it in. As
I read here, for the RS DHT a protocol adjustment is planned and
possible, maybe they switch as well to xep174.

Would you suggest this? and then.. why not a cooperation in this development?
Did you read this:

"4. Discovering Other Users

In order to discover other users, a client sends an mDNS request for
PTR records that match "_presence._tcp.local.". The client then
receives replies from all machines that advertise support for
link-local messaging. [11] The client MAY then find out detailed
information about each machine by sending SRV and TXT queries to
"username at machine-name._presence._tcp.local." for each machine
(however, to preserve bandwidth, the client SHOULD NOT send these
queries unless it is about to initiate communications with the other
user, and it MUST cancel the queries after it has received a
response). Note: The presence name to be used for display in a
link-local "roster" SHOULD be obtained from the <Instance> portion of
the received PTR record for each user; however, the client MAY instead
display a name or nickname derived from the TXT records if available."


A DHT is much better than DYNDNS or forholding the IP, which may dynamically.
So lets talk about the serverless implementation into PSI.
Why not a DHT?

Kind regards Mike
