It is my understanding that applets are allowed to:

- listen on non-privilged ports (>=1024)

- connect and accept connections from the host/server they came from

Thus it sounds like they should be able to create a server socket, and
accept connects from the server they came from. Is this not your
experience?

thanks, roland
