@TheBlackThrone: I'd think that Orgotek were probably<em>especially</em>likely to try to recruit psions with different Aptitudes. ;D  CS has confirmed that in this version of the setting, the orders often acquire people who don't match the organisation's core psionic focus - so you can probably have just about any Aptitude while being a member of whatever organisation most appeals.<br/><br/>It's also worth noting that psions can potentially have 'secondary' Aptitudes.  You can dabble in powers outside the core trio of modes granted by whichever Aptitude you were inducted into when your psionic powers were awakened: you'll never get beyond a rudimentary grasp of your secondary field(s), but those rudiments can be really cool and worthwhile in their own right.  So someone inducted onto a different path could potentially have picked up a<em>little</em>bit of electrokinesis to help with a role in Orgotek (or the like).  Even if the only thing you could do with electrokinesis was try to sense nearby flows of electricity, it'd be a useful perk for a ship's engineer!<br/><br/>-----<br/><br/>On Biotech: anyone can<em>use</em>most of it, but psions can attune to it.  There's a distinct limit to how much any given psion can bond with... but linking your 'noetic' (psi) signature to that of a part-living device can provide perks.  Some biokinetics might use their particular gifts to take that even further, adapting their own bodies to work more closely with attuned biotech devices.   However, it's worth noting that attuned items often draw sustenance from the person they're linked to... and exceeding your personal tolerance for such devices can get nasty (in the '<em>when symbiosis turns into addiction combined with parasitism</em>' kind of way of really messing yourself up).  Most psions will only have a very limited number of biotech devices, and will be wary of grabbing more... but they're also often the best tools for psions to have.<br/><br/>Non-psions can do a great deal with biotech, and Orgotek in particular has done a lot to make it fashionable around much of the world; but creating and crafting it is<em>usually</em>the preserve of psions who can link with their inventions in ways that most people simply can't.<br/><br/>But I'm speaking with the dual caveats of a) most of my knowledge of the setting being ~20 years out of date, and b) not being the GM anyway.  ;)
