My vision of skinlink wich i use very often.
does skinlink require direct contact with the user's skin (as the name STRONGLY suggests), or can it transmit through clothing (I've seen vague references to this being stated in Unwired somewhere, but I've yet to find it myself)?
It can go trough little clothing but if you don't like the idea consider that clothes have conductive parts made for that or add mod to the armor/clothe.
Can skinlink be used to directly issue commands to an item, or is it merely a method of connecting 2 (or more) devices together (I.E., is it a DNI in it's ow right, or just another way for your ~comlink~ to talk with your PAN)?
No, skinlink is just like a way of communication. I consider you need at least a DNI. Device need skinlink mod and an implented way to command it or a command program.
What's eveyone's feelings on your skin's 'dataload', I.E. how many device can you connect over your skin before the data just becomes useless noise?
No real limit like datajack. As stated in rule you should consider dataload only for huge amount of data.
Can a person with a full cyberlimb use skinlink on that limb, even though they have no 'skin'?
Yes, except if he has MDS Subdermal Sheath (rc p 35)
any other question/answers/clarifications people can com up with?
Problem is "touch" hacking
any consideration about that ?
