All the wineasio code I could find has now been committed to sourceforge SVN. Robert Reif's original code and changes are in the wineasio-0.0.x branch. The "old" JackLab code is in the wineasio-0.x branch. HEAD contains wineasio-0.7.x. Tags have been created on HEAD for each version.
Bugs, patches or requests for commit access via the Tracker, please! :)
