+* websocket_max_frame_size should be at least something like 64 * 1024,
+  maybe put it and message size at 128k just to be sure
 * test transfer again with changes made:
   * crossbeam-channel
   * ipv6/ipv4 mapping
   * tungstenite 0.11
+  * notes on testing: official tracker does not successfully handle file
+    transfer on localhost between two instances of the official client
+    (webtorrent-hybrid), probably due to sdp negotiation issues. so I
+    shouldn't t pull my hair out trying to figure out why the official
+    clients won't work with aquatic_ws in this scenario. I should probably
+    just test manually with clients on multiple machines and skip
+    automated docker tests
 * is 'key' sent in announce request? if so, maybe handle it like in
   aquatic_http (including ip uniqueness part of peer map key)
