Subject: HyperXchange

HyperXchange is a 76K HyperCard stack that gives you access to other Macs
on a local area network, using Apple Events and HyperCard (version 2.1 or
higher).
It can be used to get information, send commands and send and exchange messages.

FEATURES:
* Commands/Requests:
  A number of pre-set commands and requests are available from the Command and
  Request menus, or you can write your own in HyperTalk and send them.
* Instant Connection Buttons:
  Once a connection has been made to a remote Mac, this connection can be saved
  as a button. Thereafter, just clicking on this button will re-establish the
  connection.
* Auto-Launch:
  When you attempt to make a connection to another Mac, HyperXchange first
  determines whether or not HyperCard is running. If not, it can actually link
  to the remote Mac's Finder (Systems 7.0 - 7.1, thanks to the XCMD
"FinderEvents")
  to launch HyperCard for you.
* Broadcast Messages:
  A single message can be sent to a number of Macs in quick succession. Options
  are: "Only if..." (only send to a recipient if a certain condition is met),
  "Beep" and "Switch to HyperCard".
* Chat:
  Based loosely on the "Conversing" card of Apple's Apple Event Primer Stack.
* On-line Help
