ok, I really think it _is_ possible and we will do this, in KCL.

I'm expecting that the component library will solve most of those
multiplatform issues. Each platform has its own best-suited toolkit, so
we need an abstraction layer above those toolkits.

This is quite similar to the structure of KCL:

I personally think that it is better to start with only a limited group
of people and to add public discussions later on.

That's the reason why we started with KCL this soon. At first it was
planned to add Qt and KDE support to FPC, but after the announcement of
Lazarus and some unresolved issues regarding the compiler we decided to
start with the GTK and Win32 targets.

I don't think this is important when you have a component library which
wraps those internals from you.

But it will limit you in a way. BTW:
- DB access has _nothing_ to do with desktop environments
- Corba support is only partly dependend on it
- Media access is usually independent from it
- Desktop access: Most applications won't need it
But, the main problem is, that there are at least three different groups
- KDE fans
- Gnome fans
- People who won't use any of them
I think a RAD IDE for FreePascal is _extremely_ important, especially
under Linux; and if you choose to support *only* KDE *or* Gnome you can
be sure to have about 2/3 of the people against you.
