Yes, I also use the relaying feature to pull some *known* streams from fixed IP
servers. But in some more mobile contexts, this has 2 main drawbacks :

- each wanted mount point has to be added to the relaying server conf file. This
can be exhaustive when many mount points are needed and often changed,

- the relayed server has to be seen by the main server, that is, identified the
DNS behind any firewall routers on the network chain. This is a very common
case in my experience that implies DCHP managing, DNS rules and so on...
