Yes, I don't see a problem with that, if the quality is suitable. (read: the
code quality is good and multiplatform). 

I won't accept a linux own package, see

It is not a problem for a plugin unit (though it makes it less generically
appliable, and more a specialism).

I was talking about the default situation, where such empty attempts are not
acceptable, because it has the potential to totally break a FPC release.
