This is/was the interesting part (in combination with "DHT"). So I sign
in, the tox core/client publishes my ID with my current IP address to ...
ehm ... where to exactly?

I suppose this is not the "DNS" service explained somewhere in the
Wiki, as that sounds as if it just maps some kind of textual name to
the ID, but does not take care of the ID -> IP addr mapping.

Makes sense ... :-)

Another thing which should appear in some prominent (!) place on the
web site is a statement, that tox.chat has nothing to do with this:

When originally reading through the WWW I found that (and tox.im which
did not work (yes, explained somewhere)) and that sounds quite
frightening and might people make stay away from "our tox" here.

Many thx!!
