@russ_am Would be nice, but would also pose a few privacy, scalability, and usability concerns.

Namely, your IP being revealed to possibly multiple third parties running decentralized nodes, decentralized networks benefiting less from economies of scale, and the fact that there'd be no central notification service, which could make notifications slower. (see: how long notifications take on Session if you don't use Google's/Apple's notification servers as a proxy, often upwards of 5-30 minutes)
