Polypaudio has the possibility of reading an X11 property to get the server and auth cookie. This could be useful when using remote X11 applications (tl-run-unixapp) as they probably will not have the environment variable and the cookie file. The big issue is how we should set up ports to tunnel the data. The local port on the app server needs to be the same as the ThinLinc server as X11 clients from both machine will see the same property.
Applications on a different machine are probably not that interesting since that will require some network infrastructure as well. However local applications might end up with a slightly broken environment where this could be a useful fallback. (for local applications the fallback is a hardcoded path /run/<uid>/pulse)
