This is true. We don't show Move when the initial protocol has no support for
deleting (e.g. HTTP), but not when this particular directory is readonly.
However that's a bit difficult to find out, given that the drop contains only
the source URL... Ah maybe the dnd actions could be used so that the source
only offers Copy / Link actions when it doesn't support deleting. But I don't
think this is supposed by Qt/XDND (it's either "all actions" or "one" AFAICS)
The other option is to stat the source directory before showing the popup,
but that's too slow. And the last option I can think of, is a kde-specific data
shipped in the drag-object like we do with x-kde-cutselection (libkonq/
This kind of hack is frowned upon by people who try to implement compatible
DnD with kde/konqueror though.

You mean not showing the popup, too, then?
I hate this semi-clever behavior in Windows.
Any program which tries to guess what the user wants is bound to fail.
And any program which modifies its behavior based on something that
is more or less hidden to the user (isn't the whole idea of mountpoints
to *hide* the filesystem separations?) is bad behavior.
