using mySQL to communicate between PHP and Rev CGI Deamon

[David Beck]

Has anybody tried to use a database backend such as mySQL as an 
intermediary between a frontend like php and a Rev application running 
as a backend deamon? The idea would be to have a php script insert 
"requests" into a mySQL database, and then have the Rev deamon 
constantly querying that database and processing any requests, placing 
the output for any request processed back in the database. The php 
script would wait for the results from the Rev deamon to "appear" in the 
database, and then would display those results to the user.

Does this sound like a viable model? Has anybody had experience trying 
this out?

Thanks!
