For those who use Tor regularly for things other than web browsing: how bad is the real-world latency for pushing a ~20KB Opus audio chunk over Tor these days? Are we talking a 2-3 second delay, or is it much worse?
Also, once it's decrypted and played back, the message gets destroyed.
When remote is detected as recording this sound will play if the setting is enabled.

Added link for clarity. Seems like you could get more or less realtime, udp streaming, full duplex communication . Once you have the first part of that built, then adding things like voip or video calls or what have you becomes a lot easier.
I know you can set up mumble over Tor but it's going to have the same latency drawbacks.
Another commenter noted the ability to configure only 1 hop instead of the standard 3. I wonder how much latency would be gained back. I want to play around with this.
You could use tor to anchor a common relay, then do key and route exchange to establish veilid, then the realtime app uses that for a very secure private route unique to the two endpoints.
From what I can tell, because of the design, veilid would be excellent, comparable to many commercial voip offerings, with 150-500ms latency . More nodes and users would quickly ramp that up. There are a ton of downstream benefits of something like this; faster file exchange for ipfs, bittorent, etc, that doesn't gum up the tor layer, a kind of implicit defense in depth, but also low latency, efficient peer to peer routing.
It'd almost be zero knowledge by construction; you could build a multi-hop escrow style key exchange.
If Musk integrated tor relays and veilid peers throughout Starlink, you could get near-native latency for wherever you connect in the world, more than enough to add timing attack noise and layer in other security features.
Modulo cool project love show HN etc.
