Unlike Web Services, Remoting is a technology that can be used in homogenous environments only.  Remoting technology uses channels and formatters.  The channels provide the transport protocol and the formatters are responsible for serialization and de-serialization.  We can create SOAP channels rather than using the HTTP channels in .NET.  In such a case, we have to make use of the System.Runtime.Serialization.Formatters.Soap namespace in .NET.
