this .zip consists of five items:

- the VVSend xcode project builds a QC plugin which, when sent a string, will post an NSNotification using a specific notification name, passing the string along with the notification.
- the VVReceive xcode project builds a QC plugin which listens for NSNotifications at the same name, and outputs whatever it receives via these notifications (it receives whatever VVSend sends).
- "sendReceivePluginTest.qtz" is a single composition with both a send and a receive.  this composition exists to help test and debug the above QC plugins.
- "VDMXPlugin-Send.qtz" is a composition meant to be used as a VDMX plugin.  it simply posts the string of the current date as a notification.
- "VDMXPlugin-Receive.qtz" is also meant to be used as a VDMX plugin.  it receives the date string posted by the "send" composition, and renders it to an image which is published as an image (available in vdmx as a tap).

...as far as the plugin itself goes, there's a good deal of work to be done on it still.  for starters, you'll probably want to make it work with NSDictionaries instead of strings, i'd recommend making the name used to post the notification a modifiable parameter of the plugin (so you can have multiple sets of send/receive plugins that communicate only with each other), and i'm sure there's a cleaner way to handle working with the data.  basically, these projects exist to demonstrate that this manner of composition-to-composition communication is possible- they're not meant to be a functional part of your setup without a bit more work...
