As a former beta tester for Leechnet,all this P to P chat reminded me
   to revisit Nordic Research.They may be onto something with,"...the
   concept of cybercash one step closer to reality."
   Maybe,youse would probably know better than me."extra skin?" Caveat

   Featured product: Opticart
   Web page developers using the OptiCart system are praising that the
   website no longer has to be built around the shopping cart unlike other
   shopping cart software and e-commerce software, but is instead added as
   an extra skin after the design and implementation has already been
   made.
   The OptiCart system uses Java technology to provide real-time updates
   of the contents of the shopping basket and brings the concept of
   cybercash one step closer to reality.
