The way I understand the initial question was to proxy SSL WITH
BROWSER KNOWLEDGE.
this would be of great help for example in accelerator mode :

client --- ssl ---> Squid --- http ---> server

1- The web server would not have to handle the encryption task: gain
of performance and possibility to use an existing web server without
good ssl support
2- The traffic could be monitored for hostile activity by an intrusion
detection tool (lets say snort) on the hub between the squid and the
Web server

I agree with you, that kind of tool would also be usefull for some bad
guys willing to set-up a man-in-the-middle attack.

Anyway, Macrosoft "proxy server" can do it, since several years.
