Correct.  Just for conversation's sake, there are actually two issues
with Cybersource's new perl Simple API.  The first is that Interchange's
ICS.pm uses the older CS perl CDK, which is totally incompatible with
the new Simple API.  The second issue is that I couldn't get the perl
Simple API to install at all (I was going to write an IC payment module
for it).  I suspect the documentation for it is missing information on
some sort of prerequisite.  The older perl CDK, on the other hand,
installed in a matter of seconds on two systems I was working with.

Yes.

Yes.  IC will communicate to your customer's browser via SSL.  When it's
appropriate, IC will also communicate "in parallel" with the Cybersource
system.  Do not be fooled by the port 80 communications, though.  The
information sent to Cybersource is well encrypted, the "ecert" process 
described earlier is what creates the keys used for authentication and 
encyption.

The whole CS integration procedure may seem daunting but I found it 
considerably easier than the Bank of America integration we did 
previously.  In addition, the CS interface is much, much, much, much 
faster.  It's also a single-step to auth and settle, whereas BoA was a 
two-step process which was an issue when one step would succeed and the 
other would fail.
