Good for speed-up yes (I run it at the lab in the office). But transparent
proxying results in breaking a number of other protocols, ftp + SSL
transactions for one. [1]

Much like there are "good" reasons for running NAT, there are also reasons
why t-proxying isn't always desirable.

[1] Before someone mentions the HTTP CONNECT method, read rfc2616 first.
    Doesn't work transparently unless you've got one of those expensive
    reverse SSL connectors.
