+netinterface
+  use qca syncthread, match keystore in thread safety concerns
+  "Interface ids obtained through NetInterfaceManager are guaranteed to be valid until the event loop resumes, or until the next call to interfaces() or interfaceForAddress()." ...  the code seems to be lying about interfaceForAddress.
+
+netnames
+  support faking srv (or perhaps any record) somehow, through config or code
+  support multithreading
+    put the netnames backend into an alternate thread (this thread should
+      probably be some generic irisnet thing that other modules can use too)
+    netnames front-end api communicates with the backend, so that one backend
+      is shared by all threads
+  NameResolver/ServiceBrowser/ServiceResolver should have isActive?
+  report ServiceBrowser error codes
+  report ServiceResolver error codes
+  ServiceInstance attribs arg of constructor should be optional?
+  ServiceInstance should cache the name() answer
+  ServiceProvider should support error codes and passing many ip addresses
+  ServiceResolver should give the hostnames and the ip addresses.  hostnames
+    may be needed for SASL
+  consider reverse dns (for both internet and multicast)

+questions:
+  1) where does it end?
+  2) how would a pgp-auth for xmpp-core work?
+
+goal:
+  support xmpp-core for tcp/httpbind
+  xmpp-core should be "just another protocol"
