There are certain rules to that, wiki probably has that information 
already. For example your patches will be rejected automatically if you 
had/have access to MS source code, doesn't matter if it's available for 
general public or not. Also you can't use implementation details 
information extracted using Wine's tracing. You can't disassemble native 
modules of course. Maybe there's more but these are the most important.
