You're right in regards to PCL and MonoTouch.  I have no idea what I was
thinking.  I seem to recall a year or so ago when you ran into that issue.
 I believe WP8 supports unsigned value types, so it may not be an issue if
WP7 isn't explicitly supported.


I'm prepared for it being an arduous task.  Most of the challenges you've
listed are addressed by using PCL, except for legacy technologies.  When it
comes to unsupported platforms, I think often times the only options is to
drop support for them when it comes to new code.  Like you mentioned, we
don't really hit the support level that log4net does, we've already made
the decision to not support .NET 3.5 in the 4.x versions of Lucene.

I still think my biggest blocker against PCL is that it's not in
Express....I'd like to keep support for Express editions instead of
potentially blocking people from contributing.
