I still think that it's wrong to hardcode the IID - this would make it
impossible to replace the component by another minesweeper game.

You seem to misunderstand what OAF is aimed for; if I remember correctly, one
reason for the gnorba->OAF migration was the fact that OAF supports queries
so that you do not have to hardcode anything (btw. if I remember correctly,
the other big reason was that OAF supports UUIDs so that we won't get any
namespace clashes ;-))

With OAF, you query for the _capability_ or a component and _not_ for its name.

So IMHO the correct thing to add an attribute to gnomine's oafinfo file and then
to do an oaf_query() for this attribute.
