Yep, you can, though obviously it will be completely unportable.

can do that?? 

That's effectively unknowable information without something at both ends
though. tcp_get_info will give you an incling, but not much of a useful
one IMO. 

For this kind of stuff it's more typical to use tools like netstat, tcpdump,
lft (layer four traceroute) and so on - instrumenting Apache directly
seems unusual, but it would work :-)
