AOLserver works very well in most environments, now that the memory
leakage problems with Tcl 8x have been solved. Problems with FreeBSD
that folks have had aren't at all representative.
The problem with Apache 2.0 is that someone will need to support
mod_aolserver now that ArsDigita is no longer doing so. If someone's
willing to take that on, then I see no reason why we can't support
Apache 2.0 + mod_aolserver.
Thus far no one's offered to take up support of mod_aolserver...
