This is not entirely correct - I have come across problems communicating
over socket interface when no NIC is installed even when addressing the
'localhost' interface. My advice is - since many motherboards come with an
on-board network port and/or NICs are so cheap - "splurge" on a NIC.
Furthermore, since you are using sockets I assume you might want to actually
communicate across the network sometime - otherwise, you can use shared
memory/pipes/etc. for communicating between processes in the same host -
TCP/IP stack (socket) is an overkill for this...
