Show HN: ProxChat – A Local Buddylist

I created this entirely on a lark (thanks Claude), based on a half-remembered app from the early 00s. Does anyone remember something similar? It was an awesome little lightweight way to chat with fellow conference-goers.

My recollection is it had a name (not proxchat) that was entirely unrelated to communication. Something like ... Pinetree? Platinumpad?
