Software patents don't work where there's "prior art", so you should
be safe.  Software patents are not valid in the UK, and other free
countries, so I'm safe whatever.  :-)

Take a look at the mini-cart on http://www.diy.com/.  It sticks out
like a sore thumb and inserts a large "The item above has been added
to your basket" block under the ordered item.  The site doesn't run
Interchange, but it shows that the mini-cart idea works and is in use
on busy sites, which further re-enforces the prior art.
