Andrew, thanks for your reply, will ask over at the AOLserver list. I'm not even sure if it is futile effort, but with so many good PHP applications out there that would make an OpenACS installation look considerably better, interaction between both worlds seems like a good thing to me .
What I could envision e.g. for the moment is to use a PHP address book functionality in OpenACS and redirect the Database inserts (and reads, maybe) through Tcl API, so both OpenACS and the PHP address book could add items, but you could view it quickly in a list-builder page (which is easy to generate).
I'm tossing out ideas here at the moment with a huge potential for trouble, but, as a matter of fact, OpenACS lacks functionality in a number of occasions, where (specialized) PHP products are further advanced. It is just a question of how to integrate these best.
