Hmm... a good question.
As I pointed out earlier, the tech information is still in development, and one of the big areas not done is technological items (other than firearms, anyway).
I'd say that you can probably find technological equivalents of most magic items... if you want one, please post a quick blurb on how/why you think the tech equivalent would work (you don't have to get real detailed, but just some ideas), and I'll see if it fits my thoughts on technology.
Bracers of armor... I suppose might work... go ahead with it for now, when I start work on the tech book again (I've been really busy since school started, so I don't know when that will be) I'll see if it fits.
Oh, and the IC thread may be delayed... it will probably be posted sometime tonight, but it might not be up until tomorrow. Saturday at latest.
