I kind of like the idea of re-working cloak disruptors into a catch-all cloak/jump drive/jump scanner/etcetera interrupt. Sure, it would still be a reactionary tool, but at least then it would be reactionary to everything, which might encourage a little more use. Perhaps then we might see a few more Grizzlies and Democritus' out there, since they have that sweet, sweet extra CM slot.
@nOmnomnOm I'm not sure about jump ranges, as I do not own a drive myself, but did @sindroms mean that all jump drives can be used to jump twice per full charge, rather than having a 2-system range? I'm not sure about the wording of the original post, but that's how I read it.
