The current mod_ssl works by simply handing over the socket fd to the OpenSSL 
library and letting it do reads and writes (by way of the BIO_s_fd callbacks)
as it sees fit.  To make the reads and writes happening inside OpenSSL go to 
bucket streams instead, you have to write a class to replace BIO_s_fd.

I think there is a good argument to be made that SSL should be implemented as
a replacement for the socket layer, that's why it is named Secure Socket
