>From what I understand from the sources (find_sources_in_groups in
donkey/donkeyClient.ml, see
http://savannah.nongnu.org/cgi-bin/viewcvs/mldonkey/mldonkey/donkey/donkeyClient.ml?rev=1.19&content-type=text/vnd.viewcvs-markup
), when a new client is contacted, if it is another mldonkey client it
receives the list of sources we have thru TCP; Otherwise, it receives the
list thru a sequence of UDP packets, (at "edonkey tcp port+4", so right now
it doesn't do much good, because other edonkey clients use a random UDP
port instead). 
Once this is done, the new source is published to all the other
sources we know about, thru UDP.
In the end, the new source is added to the list.

The TCP and UDP packets sent are "faked sourcereq replies", mldonkey didn't
invent new packet types for the purpose of source propagation.

(Please correct any mistake...)
