Great! It would be nice to see a patch/svn diff if you have one available.

I think for now that should be sufficient for the users with urgent SNMPv3 
requirements, but other methods (e.g. SSL certificates) would be useful later.

Cool.

I'll have a look as soon as you send me a patch, but ideally we would want to 
be able to access both transformed and non-transformed values. Otherwise, we 
will have to consider adding template versioning and have devmon check that 
the templates are up-to-date ...

We will definitely want to ensure that all values used in thresholds or RRDs 
are maintained or migrated.
