im not a delphi coder, but i guess that there are some issues in porting some app that not use only the vcl from delphi/kylix
so as the hfs does use some other libs that are not linux native, it is more harder to do than we can think....
but the development is opensource, i got the kylix and i canot compile it on linux, but i have not started to debug why this happen yet....
maybe when i got time....
