I just looked, and there aren't *that* many msi and ole bugs reported in bugzilla.
http://bugs.winehq.org/buglist.cgi?product=Wine&component=wine-ole&k... lists 37 ole bugs with downloadable demos
http://bugs.winehq.org/buglist.cgi?product=Wine&component=wine-ole&b... lists 89 ole bugs total
http://bugs.winehq.org/buglist.cgi?product=Wine&component=wine-msi&k... lists 35 msi bugs with downloadable demos
http://bugs.winehq.org/buglist.cgi?product=Wine&component=wine-msi&b... lists 71 msi bugs total
Would it be unreasonable to set a goal of having all msi and ole bugs fixed for wine-1.0 ?
