Most KDE technologies are C++ based which is hard to swallow for other
projects using C. Also they are using Qt facilities which make
programming much easier, but hard to adopt by others due to licensing

What do you mean by "behind"? It has some unique features (like indexing
nested archives). And Tracker is not "standard", it is an app.
Freedesktop should provide specification of indexing service, not
implementations (apart from infrastructure, like DBUS).

Solid is higher level library than HAL. And it must work also on Windows.

Regarding Solid/HAL - it won't. Solid will _use_ HAL as a backend.
As for other core services, I would like to see cooperation too.
But I guess it won't happen until Gnome starts using objective
interfaces (C++) instead of plain C (disclaimer: it has been a long time
since I had seen any Gnome service, so please correct me if I am wrong,
maybe Gnome is using C++ already?).

My 2c.
