The only reason I wanted to do it was because the ACS core seems like a lot of overhead, especially on ones database, especially if you want just one app from it. PLus, and this is probably just me missing something, but I just can't seem to make ACS work unless it's my top level page(all links are back to your root, and if it's not the ACS root page, it doesn't work), like I said, I'm new to AOLServer/OpenACS and just havn't had a lot of time yet to play with it and am probably missing something basic.
I have installed ACS, and it is really a wonderful thing. I san see many hard years of work here.
