I am no licencing expert but if your not using the exact code from POI but 
instead writing your own code that is in a totally different language and 
only using POI code as a guide, are you still binded by the Apache licence? 
And would this fall into the same catagory as a GNOME(Ximian, or whoever) 
implementation of .NET? Using .NET as a guide they are developing their own 
libraries.
