Well rewriting a whole bunch of files is a lot of work, but a good idea.
How can you rewrite something, which src's is available without copying
at least parts of the code (m-files)???
If there is a copyright on it than it is probably also on parts of it.
Where is the border (how many loops, which variable names)?
I think this is a VERY undefined region. Any ideas?
When I want to rewrite a whole toolbox it should be at least 100% 
compatible +more features. Otherwise I have really big problems here
whith the "productivity line" running on matlab.
