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
