Comment (by kaie):

 What do you think about the following alternative approach, which would
 make it unnecessary to improve the internals of transport plugins?

 - allow tor to spawn multiple instances per transport type
 - introduce some sort of aliasing, which allows the use separate transport
 configuration lines,
   where each use a separate alias name as the key

 For example:

 #                    alias        transport-to-execute
 ServerTransportAlias second-obfs4 obfs4
 ServerTransportAlias third-obfs4  obfs4

 ServerTransportListenAddr obfs4        1.2.3.4:443
 ServerTransportListenAddr second-obfs4 2.3.4.5:443
 ServerTransportListenAddr third-obfs4  [2001::2:3:4]:443

 ServerTransportOptions obfs4        "abc"
 ServerTransportOptions second-obfs4 "def"
 ServerTransportOptions third-obfs4  "ghi"
