A four-way exchange in basketball

A regular reader alerts me to a four-way exchange in basketball (for all of you who thought those were just for kidney exchange:)
"Wednesday's four-team trade between Houston, Indiana, New Jersey and New Orleans featured the Hornets' young point guard, Darren Collison, going to Indiana, and the Rockets sending forward Trevor Ariza to New Orleans. The Rockets also got guard Courtney Lee from the Nets, while the Nets acquired forward Troy Murphy from Indiana. Indiana took on veteran forward James Posey from New Orleans to complete the deal."
