INTRODUCTION

  Speak Freely is a Public Domain Internet telephone for Microsoft
Windows that allows you, with a 28.8 Kbps modem and sound card, to
send and receive audio, in real time, over a computer network.  If
you're connected to the Internet by a sufficiently high-speed link,
you can converse with anybody else similarly connected anywhere on
Earth without paying long distance phone charges.  Users can find
one another, even if they have dial-up connections to the Internet,
by publishing and searching directory entries on a Look Who's
Listening server.  You can designate a bitmap file to be sent to
users who connect so they can see who they're talking to.

  Speak Freely is better than using your regular telephone not only
because you aren't running up your phone bill, but also because your
conversation is secure from eavesdroppers.  Speak Freely provides
three different kinds of encryption, including the same highly-secure
IDEA algorithm PGP uses to encrypt message bodies.  By using PGP to
automatically exchange session keys, you can Speak Freely to total
strangers, over public networks, with greater security than most
readily available telephone scramblers provide.

  Speak Freely for Windows is 100% compatible Speak Freely for Unix,
currently available for a variety of Unix workstations.  Windows
users can converse, over the Internet, with users of those Unix
machines.  In addition, Speak Freely supports the Internet Real-Time
Protocol (RTP) and the original protocol used by the Lawrence
Berkeley Laboratory's Visual Audio Tool (VAT); by selecting the
correct protocol, you can communicate with any other network voice
program which conforms to one of these standards.

  Multicasting is implemented, allowing those whose networks support
the facility to create multi-party discussion groups to which users
can subscribe and drop at will.  For those without access to
Multicasting, a rudimentary Broadcast capability allows transmission
of an audio feed to multiple hosts on a fast local network.

  NOTE: Both parties must be using Speak Freely or a compatible program
in order to communicate.  Speak Freely cannot be used to call a regular
telephone number.

INSTALLATION

  To install Speak Freely, unzip the files into an empty directory.
You will probably also want to create an icon or shortcut to the
"speakfre.exe" file to make life easier.

  See the Quick Start Guide in the Online Help for the quickest way to
get up and running.

DISTRIBUTION

  This non-cryptographic version of Speak Freely, nicknamed Spook
Freely, may be freely distributed anywhere.  See the Speak Freely web
site for links to the download site in Switzerland for the encryption-
enabled version of Speak Freely.

WHY NO ENCRYPTION?

  Some governments believe individuals shouldn't be able to have
private conversations and attempt to restrict the use, distribution,
or export of software that provides communication security through
encryption. The standard version of Speak Freely includes encryption;
if you are worried that using or redistributing such software (for
example, placing Speak Freely on an Internet site or public bulletin
board system) might violate the laws of your jurisdiction, you can
distribute this version of Speak Freely (nicknamed Spook Freely)
which has all encryption capability removed. This version tells its
users where to obtain a copy with full encryption capability, should
they desire to do so.
