Clootie you are right in principle but there are simply too big differences between FPC and Delphi so this project is not possible, for a start FPC doesn't support packages (Laz recompiles itself), the {$R resfile} directive is not supported by Unix systems like Linux and FreeBSD, also FPC is specialised in working with .inc files and various crossplatform coding techniques wich Delphi doesn't know, all these are going to make life verry hard for the people attempting to do this.
In theory the project is good and if FPC supported at least packages the project would be possible, but at the moment i don't see how you will be able to install components.
Let's hope i'm wrong and the project will teach us some good things after all.
There is also another problem for those wich don't have Delphi, this means the have to buy it before using it with FPC but only 2005 is available wich is buggy and quite expensive.
IF the project will be usable this means that we will be able to use the LCL in Delphi wich is also a verry good thing.
