i'll check it out.  i experimented around, and currently melting gossip and amethyst with a list that's 3500 (.298mb).  It's chewing through it though, very interesting.  This size was about as large as I could get before hitting a problem somewhere with ndk.Publish, or the relay itself (although I set the relay to allow very large lists, so it should have worked to go up to 10k events and ~.9mb.
