Bug (Enhancement) #667 addresses this.  There is a comment which says 
there is a preliminary tutorial done and it should be incorporated into 
the encyclopedia ASAP.  So we should see something soon.

I found the article by Tim Monroe in MacTech magazine very helpful 
(September, October and December 2003).  At the time I didn't subscribe 
to MacTech so I just ordered the individual issues online.  You could 
also look at source code from the EnhancedQT external I've worked on 
<http://mangomultimedia.com/developer/revolution/enhancedqt.html> or 
revzeronconf from Alex Rice 
<http://mindlube.com/developer/revzeroconf/index.html>.  Those might be 
helpful.

In the source code for the EnhancedQT external there are some useful 
functions that Tuviah shared with me for dispatching messages to 
Revolution objects and changing native paths to Rev paths.  That might 
be helpful.  Look at the ExtUtilities.c file.

You can get the SDK here: 
<http://www.runrev.com/revolution/downloads/distributions/>.  Just 
click on the sdk folder.
