gollark: As long as CBOR and websockets are available in Amulet it would be possible to implement the skynet client in that, it's not very much code.
gollark: Well, good to know, but I can't particularly be bothered.
gollark: How do you manage IO in amulet exactly?
gollark: Advance warning: skynet service may be going down in the near future because I need to rework my horrible mess of a server setup, please consider switching to alternate skynet servers, more information will be provided if I actually do decide to have some downtime.
gollark: I should test this.
