Huh, I'm trying to pick this up (after 3 years...)
Honestly, currently my IQ seems to be less than satisfactory to understand
and utilize the advice. (It's also almost 40 degrees C here so I'll have to
think out loud...)

- is the SSSAD in s-abstractions recent enough for these tricks? (
http://code.google.com/p/s-abstractions/source/browse/#svn%2Ftrunk%2Fsssad)
- is there an example patch of SSSAD local saving available? i just wish to
see/understand how to save and load presets exclusive for an abstraction
instance.
- or, please, is it possible to list the steps of creating SSSAD local
saving for an abstraction? (eventually using [presetstore]... which I have
attached because it's not hosted anywhere any more)?
- is at viable at all to avoid using rjlib for this (and to use 'pure'
SSSAD), or I couldn't get away without all that patching that is in
u_loader, u_dispatch, u_cocollect etc?

...sorry for the dependent mental state in which I am! :-o
