Peter,
I am curious if you've had any experinece with Google Mini or Google Search Appliance and DMX.  It would appear that I am being forced into making a Google Mini or Google Search Appliance (GSA) box work within our enviornment.  Do you know if the either of these two devices will work and keep document security in place?  I know the Lucene search provider that comes with DMX will and haven't had much time to play with the other search providers that come with DMX.  Basically what I need to know is if I have access to a secured document within DMX will the Google Mini or GSA be able to return the proper results?  I did see where unprotected documents can be searched by google but it's the protected ones we need to ensure are working.  
Thanks in advance,
Arick
