I missed this back in November, but Sun is opening a RFID Test Center near Dallas. The center will allow Wal-Mart suppliers to test their RFID implementations for compliance with standards set by Wal-Mart.
I have created several databases of RFID related information that may help you find information that you need to assess an RFID Opportunity
You can look for RFID manufacturers, consultants and software companies, RFID Applications and the related companies, as well as numerous RFID Implementation white papers.
There is also a vibrant forum where experts share their RFID implementation experiences
Hope this helps
