Thank you kindly, MCortez for a patch that:

With some support from HomerH, this patch adds support for Wind Model plugins via the mono.Addin framework. * Adds console & OSSL access to Wind Parameters * Adds plug-in support for custom wind models * Provides two example Wind Model plug-ins Documentation for the wind module is temporarily located at http://code.google.com/p/flotsam/wiki/CoreWindModule [^] -- will move this documentation to http://opensimulator.org [^] after the patch has been committed.
