Very hard to say; people differ widely about the deployment footprint  
of proxies, regardless of version. if you can get your hands on a  
popular Web site's access logs :), you could look at the Via header's  
contents, although some number of proxies will not append it (as  
previously discussed).

I would point out that Squid is by far one of the more popular  
choices, especially in small ISPs, 2nd- and 3rd- world countries,  
etc., and it's still HTTP/1.0 (although 2.7 will have a HTTP/1.1 mode,  
and from the testing I've done, it's pretty conformant).
