Yes.

With the prerelease2 it will be also possible to use the same port
for all connections:

connection {
host alice port 7010;
host bob port 7001;
protocol C;
}
connection {
host alice port 7010;
host charlie port 7010;
protocol A;
}
connection {
host bob port 7010;
host charlie port 7010;
protocol A;
}
