+qcp is an application to share files on a local network; it
+was inspired by http://www.fefe.de/ncp/.
+
+design goals for qcp:
+ * offer files for "multiple" downloads (ncp offers data only for one client), i.e. "server" or "persistent" mode
+ * offer different sets of files (ncp can only offer one download as it uses always the same tcp port 9002)
+ * discover downloads via multicast DNS-SD (avahi) instead of broadcasts
+ * different tools:
+   * qpush: for simple one time push
+   * qpoll: polls the first "one-time" share it discovers
+   * qcp: gui for managing persistent shares / downloading other shares
+ * abilility to limit bandwidth
+
+In order to use avahi from qt there is libqtavahi:
+ * Signal/Slot based avahi api
+ * a QAbstractItemModel
+
+qcp uses "_qcp._tcp" as mDNS-SD type; so to fake a share you could use this:
+ $ avahi-publish-service 'test share' '_qcp._tcp' 9876
