They look fine. There is just one thing: AIUI, on the sender side,
instead of inserting a send right and then using

Errr, no, in my tests the two programs have the same behavior in stream
and dgram case.  I would be extremely surprised if the two program had
different behavior since they're basically exactly the same apart from
the variable names.  I wouldn't have been surprised that stream not
support passing ports, but it seems to actually be implemented, which is
good :)

So passing the rendezvous port seems to be working fine:

ident_socket_recv.c: p_pid = 1240
ident_socket_recv.c: Socket file descriptor = 3
ident_socket_recv.c: Receiving via datagram socket
ident_socket_recv.c: __socket_recv() returned 30 bytes
ident_socket_recv.c: Received data = 0
ident_socket_recv.c: rendezvous port = 56

ident_socket_send.c: Socket file descriptor = 3
ident_socket_send.c: Sending via datagram socket
ident_socket_send.c: rendezvous port = 54
ident_socket_send.c: Sent p_pid = 1241
ident_socket_send.c: Sent data = 12345
ident_socket_send.c: __socket_send() returned 30 bytes

and with an extra pause() before the proc_user/server_identify call:

# portinfo -t 1240 1241 
    54 =>     56: send

i.e. port 54 in the sender (1241) properly appeared as port
56 in the receiver (1240).  Now you need to check that the
proc_user/server_identify RPC properly passes ports to the proc server
so that the port name gets the same there.
