IBM announced their new Software license policy for UltraSPARC T1 chip based Sun Servers. A 4 core or 6 core T1 chip requires 2 software license entitlements and a full 8-core T1 chip requires 3 software license entitlements. (Its a win-win considering before this announcement it was 8 software license entitlements for a 8-core T1 chip.
One thing to also note that a Sun Fire X4200 /X4100 with dual core Opterons require 1 license entitlement for every dual core chip. (Read the foot note for descriptions of "Multiple server families" which includes SunFire x64 servers.
The best way to distribute the news is to point people to the PDF Copy of the IBM Software License Policy
