> Is there an easy way to disallow SNS other than defining a new node type =
and setting all new nodes in this type, so I can get ItemExistException on =
save to prevent SNS from happening?

The nt:folder doesn't allow SNS. If your application doesn't like
nt:folder, you may create a custom node type like following sample.
It's the same as nt:unstructured except the SNS validation.

	<nodeType name=3D"nt:nosamesiblings"
		  isMixin=3D"false"
		  hasOrderableChildNodes=3D"true">
	    <supertypes>
		<supertype>nt:base</supertype>
	    </supertypes>
	    <childNodeDefinition name=3D"*"
		          defaultPrimaryType=3D"nt:xunstructured" sameNameSiblings=3D"fal=
se"
		          autoCreated=3D"false" mandatory=3D"true"
		          onParentVersion=3D"IGNORE" protected=3D"false"/>
	    <propertyDefinition name=3D"*"
		                requiredType=3D"undefined"
		                autoCreated=3D"false"
		                mandatory=3D"false"
		                onParentVersion=3D"COPY"
		                protected=3D"false"
		                multiple=3D"false"/>
	    <propertyDefinition name=3D"*"
		                requiredType=3D"undefined"
		                autoCreated=3D"false"
		                mandatory=3D"false"
		                onParentVersion=3D"COPY"
		                protected=3D"false"
		                multiple=3D"true"/>
	</nodeType>

As this node type could be interesting for some people, it might be
good to provide by default.
