Since you're concerned about firewalls warning about connections, I'm
guessing you're thinking about Windows. In that case, you can't use
IReactorUNIX and IReactorUNIXDatagram, which would perhaps meet your
use case (although for all I know, some firewall software warns about
There is no support for communicating over arbitrary pipes in Twisted.
There is incidental support for communicating with pipes connected to
another process created with reactor.spawnProcess, but the process API
is not the same as the IProtocol API.
In general, using pipes will lessen performance anyway.
