I must say I don't have a lot of experience under FPC or even, under Unix yet, altough my computer being a dual boot machine since a long time ago, and I have a large experience on Win32 programming with Delphi or Visual C++. So some questions may be about the FPC itself:

Is that true, or Lazarus/FPC is already capable of storing every published property? For every object should I declare a Load constructor and Store method and then call RegisterType (from objects Unit)?

You are confusing Objects with Classes. LCL uses classes, not objects.

The FPC classes streaming system is implemented to be compatible with
Delphi's. It has been implemented in such a way to make it extendible
(e.g. storing forms as XML would be nice)
However, at the moment, there is no other implementation then the text
streaming or binary streaming as implemented in Delphi.

Note that FPC does not yet support resources on all platforms, which makes
it necessary for Lazarus to use some tricks to be able to store and restore
forms from "resources".
