Release 6.1 now available! This release is a 32-bit application which runs in 
native mode on Windows 95 and Windows NT. Starting with Release 6.1, Speak Freely 
for Windows will be released only for 32-bit systems. Users of 16-bit Windows 3.x 
systems can continue to use Speak Freely 6.0, which remains available and can 
communicate with later releases without difficulty. 

Speak Freely is a Windows application that allows you to talk (actually send voice, 
not typed characters) over a network. If your network connection isn't fast enough 
to support real-time voice data, four forms of compression may allow you, assuming 
your computer is fast enough, to converse nonetheless. To enable secure 
communications, encryption with DES, IDEA, and/or a key file is available. If PGP 
is installed on the user's machine, it can be invoked automatically to exchange 
IDEA session keys for a given conversation. Speak Freely for Windows is compatible 
with Speak Freely for Unix, and users of the two programs can intercommunicate. 
Users can find one another by communicating with a "Look Who's Listening" phonebook 
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 supports Internet RTP protocol, allowing 
it to communicate with other Internet voice programs which use that protocol; in 
addition, Speak Freely can also communicate with programs which support the VAT 
(Visual Audio Tool) protocol.
