Is there _any_ chance of it? Maybe. However experience says that 
problems like the one you're reporting are generally very environment 
dependent, and if no one has jumped at the opportunity yet then it's not 
likely to happen, or at least not soon.

Not to put too fine a point on it, but doing your part in situations 
like this is part of the "cost" of "free" software.


Good luck,

Doug
