Maybe :-)

Secure mod_perl - i.e. mod_perl in an Apache that's shared with other web sites

mod_perl in any language supported by Linux

Interactive debugging of your perl on live requests inside a live Apache

See http://user-mode-linux.sourceforge.net/slides/wvu2002/wvu2002.htm

The section that's relevant here starts at 
	http://user-mode-linux.sourceforge.net/slides/wvu2002/img9.htm

There are also some wackier possibilities which I'm not sure are terribly
useful or practical, but would still be interesting to look at, such as:

Treating HTTP requests as processes, so
	# ps uax
	...
	apache    1120  0.0  0.6  4388 1536 ?        S    13:46   0:00 GET / HTTP/1.0
	...
	# kill -9 1120
or
	# nice -20 1120

Treating HTTP requests as packets and using Netfilter to manipulate them.
