The Vixie Interceptor is really the only product on the market that
handles this particualr situation correctly - it is a fine product in that
respect. Paul and his group - worked thorugh that issue with very fine
detail.

To the best of my knowledge Digex is using the Inktomi/Alteon solution.

Odd.  The box we used to sell through Mirror Image Internet has no problems
reaching Cybercash's site -- though I'll admit that we had a lot of angry
customers for a long time while we found all the wierd little unspecified
protocol violations that "just work" if no "hijacking" takes place.

I don't think Digex is using one of our boxes, and if they are using one
of the "just run Inktomi software on a Solaris box and put an Alteon next
to it" then there are going to be some wierd little unspecified protocol
violations that only Alteon, and a new protocol between Alteon and Inktomi,
could fix.  (Our box integrates forwarding and "hijacking" and this is why.)

The box we built was designed for access providers -- you know, put 1,000
modems in a room and sell dialup accounts.  It works fine in that context.
And, dialup users are usually not terribly deep as technologists, and they
are used to having their bits mutilated in the great cause of "overcommit."

While a T1 data rate would present no real problem, a T1 customer who would
usually recognize what was happening to them AND care about it, *would*
represent a problem.  And besides, a T1 customer would probably be willing
and able to use ICP or at least run their own local cache and point their
browsers at it nontransparently.
