Sweet! Very cool tool and can directly think of a few nice use cases for it.
Something to demo the "real-time" aspects is to use it together with IPFS's P2P pubsub functionality.
ipfs daemon --enable-pubsub-experiment
# Daemon now running with pubsub
ipfs pubsub sub mytopic | nc seashells.io 1337
# And now, everything you publish to "mytopic" appears on the seashell website
ipfs pubsub pub mytopic "Hello World"
# See content on website
