GMS can provide this kinda lowlevel building blocks, but they wont be used i

Yes. Every time a node is created OR a relation betweem them is created, I want to have
sort of authetication takeing place. I'm thinking about manual OK-ing a node once to make
loadable for the system, and calculating a CRC to authenticate. Overflow has a fixed
number of
static nodes, so securing node-creating will be much easier.

But the real problem comes for the authentication of relations between nodes. It wont be
to allow a relation between (overflow type) node A en node B, because it cant be determind
the chain-of-nodes ending into node A will do. In gms authentication between a Collector
and a
Visual will be implemented, and there wont be taken heed of the filters in between. All
and visuals are crc-unique, so the relation between them can be authenticated.  Not having
a system will lead to unacceptable exploiting.
The security system I've in mind is taking much more into account, but relation-creation
is by far
the most important part.

Yes. But not 100% of both :)
