In building up the background of trying to explain fiction-wise how two past characters, Mjalnar and Calliste Gessenier were in fact two current characters, Hevaima and Veikitamo Gesakaarin I created a system where they had shot out facilities into the interstellar void using technology based on colony ship warp drives. They were a combination of fluid-router hubs and mainframes made out of what is a combination of clone brain gel matrix and synthetic neuron wetware.
If they wanted to do an identity theft as they did they would kidnap the required targets and kill/hardscan for storage in a facility. They could then become the people they have killed or store versions of themselves by hard-scanning to a storage facility, copying the data into the gel-matrix and then sending off another copy into a fresh clone and brain elsewhere.
For CONCORD though it would probably just look like they had just jumped between jumpclones because the carrier signals are amended to appear as if it was a transmission between A to B, not A to C then B.
For myself though, I think I've just preferred to maintain the illusion IC that the characters using such technology are of course, "normal and typical", and not some kind of strange gestalt infomorph consciousness.
Addendum: Something ate my point.
I guess what I'm trying to say is that lore-wise it's always been possible to do lots of things regarding clones and such that are PF/lore viable. However, I suppose it's always a question of what the purpose is to do so. For myself it was not only just as IC explanation for myself to ensure a degree of internal consistency, but because I found it interesting to explore things like consciousness, identity, and psychology from a post/trans-human POV.
It has lead to some engaging insights for me as far as a character being a capsuleer infomorph goes, and has created the potential for some fiction-writing ideas which would be a mindfuck. However as far as roleplay goes, most of what I see done with clones seems to just get thrown into other people's faces as nothing more than a device to garner attention and nothing more, mostly.
