Squid can do transparent caching but that requires some effort. Squid is
not a "box" that you buy, power up and use in 2 seconds. It is a software
package that needs to be installed. It requires an OS etc etc. Now there is
no reason for a company to build such a kit and sell it a "plug-and-play"
device. If you stick with a basic (or a few basic) configurations this can
be done with ease.

I do not want to advocate Squid. I use it and am very happy with it.
Actually my squid on Solaris 2.5 (on a 5 year old Sun Ultra-1) managed an
up-time of over 400 days last year (and then construction in the server
area forced me to power it off)

The main issue is that configuring/installing servers is not easy. It
requires time and skill. If it is the first time you install something you
need to learn. This is the main issue with Squid (and any other server package)

By the way not the whole world is doing transparent caching.... The
majority just configures a proxy. This is simple and just as (if not more)
efficient. If the proxy setup is complex use proxy auto-configuration. If
you want to force users to use the proxy, just block direct access to port
TCP port 80 in your router (you will have 100% using the proxy within a few
days)

If it is real-time (like radio) caching would be useless and actually I do
not see how that will work. Non real-time could be cached and if it uses
http squid could (in concept) cache it if the expire-info does not prevent
caching in the first place.
