So I noted that one of the new elements introduced in TH is a rules-set for characters undertaking biomorph body mods without a healing vat (p.200). It makes this a 'surgical' procedure, but this seems rather far-fetched to me, given the way nanobandages and other H+ technology in EP works. Obviously some modifications are more difficult than others, but it seems to me that some modifications could be made by injecting programmed nanites on-site to reconfigure existing tissues rather than implanting new ones. This would work best for relatively similar modifications to existing structures, for example adapting salivary glands to produce toxins as part of the saliva. Obviously, some bioware would be far more difficult to manage in this fashion: a clean metabolism would not only take some time, but the replacement of intestinal flora and adaptation to the new systems would probably be quite uncomfortable to go through [i]in situ[/i], unless your site was the head. Growing major structures 'from scratch,' such as prehensile feet or a prehensile tail would most likely be problematic and incapacitate the morph for some time. Enhanced vision would probably prevent the morph from being able to effectively use the sense in question until it was fully working and integrated (the intermediate formations in the eye would most likely not provide clear data). On the other hand, muscular augmentation would seem likely not to 'get in the way' while it was in process. A structural mechanism similar to the fashion in which osteoblasts produce bone could perhaps be used for installing biological armor (bound to be an itchy and uncomfortable process, as anyone who's had to deal with major bone repair can relate). This could handily provide a sort of blueprintable 'injectable upgrade' for people operating in restrictive environments, provided they had time for it to take effect (give the speed with which nanites can strip flesh and build other structures I imagine this would take longer than surgical implantation but has the advantage of, well...Not requiring a surgeon or surgery). It also strikes me as appropriate for certain cheap, cosmetic biomorph modifications such as eye color or even self-installing nanite tattoos (or tattoo removal) in a dermal patch, just takes 2-4 hours, then the nanites go inactive and flush themselves. And hey, it only takes one cheap manufacturer getting their stock infected to cause potential issues for the PCs. Any thoughts?
