The documentation [states that](https://mediasoup.org/documentation/v3/mediasoup/api/#PipeTransport) the pipe transport uses plain RTP and RTCP to ship data over the network between 2 routers (on same or different hosts)

Is it possible to use SRTP instead? In a scenario where multiple mediasoup servers that need to connect to each other are spread around the globe, securing the connection is vital.

Pipe transports are intended for interconnect routers in different workers that maybe located in different servers, but it assumes perfect connectivity between them. In fact mediasoup disables RTCP NACK in pipe transports. So private networking is assumed so no much need for SRTP.

RTX/NACK and SRTP are being added to `PipeTransport`. See [https://github.com/versatica/mediasoup/issues/352#issuecomment-591723246](https://github.com/versatica/mediasoup/issues/352#issuecomment-591723246).
