Yes, check each of those two, there are hacks available that center around buying (say) RedHat's secure webserver (or whatever they call it) retail package for about $90, taking out the BSAFE library, and then using it with AOLserver.
It's all perfectly legal because the RedHat distro includes a binary license to use BSAFE (that's one reason it's relatively expensive) and there's no license restriction regarding using it only with Apache or whatever.
I think this is discussed in the most detail on the AOLserver mailing list. It's an AOlserver, not OpenACS issue...
