Certainly, if you want a server to make a call to an object in a client that
is behind a firewall, you cannot use TcpChannel. It is not designed for
that.

However, this is a limitation of the TcpChannel, not a limitation of
Remoting. It is possible to implement a remoting channel that allows
bi-directional communication between a firewalled client and a server. For
example, a SMTP/POP3 based channel ;-). The remoting infrastructure is
indeed very flexible.
