People who are simply *using* IronPython are covered by the license.

The originally-expressed concern was that looking at the IronPython source
code might "contaminate" a developer such that, if the same developer later
worked on a different project with similar architecture, it might open that
project up to claims of violating a Microsoft patent.

I am not a lawyer, but this seems highly unlikely.  "Independent
rediscovery" does not protect you from claims of patent infringement, only
from copyright infringement.
