Subject: Intercom!

Intercom! is a "poor man's" voice intercom, usable by any machine that is 
capable of running HyperCard 2.1.  It offers "near real-time" text AND 
voice  communications, for those with older Macintoshes that don't have AV 
capability.  It allows people to send voice and/or text messages over an 
Appletalk network, by recording a sound in HyperCard, saving it to a file, 
and copying  the file over the network.  When it hits its destination, the 
file is automatically opened, and the sound automatically played.  This 
creates a "near real-time" environment, that is quite acceptable for those 
with lower-end Macintoshes.
