Thanks, Konrad. I have a little test working, but I'm puzzled by one thing. If all I want to do is subscribe to individual channel ids (Longs, not Strings), the SubChannelClassification doesn't seem appropriate. But the LookupClassification requires overriding mapSize, which makes me think it's not suitable since I have a large range of possible channelIds. I can certainly synthesize a string classifier like /event/<channel-id>, but I thought I'd ask.
