[Zope] getting parent in product

[Dylan Reinhardt]

If you don't want to override this method (and it's not clear why you
wouldn't) you can bring about the same results by having a cron job
periodically evaluate if anything has changed since last time the cron
job was run.  

Once you've established if any changes have been made, then you can fire
off other scripts to handle them as required.

This approach will build some latency into the whole notification
process, but depending on your requirements that might be acceptable or
even preferable.  It will assure, for example, the SMTP problems won't
prevent your users from uploading files. :-)

HTH,

Dylan
