Federation Web Site
• We’re seeing about 1500 page views per day at present: significant use
• That has been pretty stable for 11 months, although federation itself has grown
• Perhaps people use the site when they’re joining, but not afterwards?

Data 12-Jan-2007
Software
• Shibboleth dominates
• Almost all 1.3: only 3×1.2, 2×2.0
• If other software supported large scale federation, more people might use it.
• Need to determine how much to let technical holes in other software hold us back
