What I mean is that I currently have a security cable that attaches to the security slot in the back. (Actually, there's this screw-on nut that attaches to the slot and then the cable attaches to the nut.) I'd like to keep that configuration. Is there space in the dock for it, and is there a hole the cable can go through, or free space to drill such a hole? The whole mechanism, when attached sticks off of the back of the empeg by about an inch and a quarter, which is significantly deeper than the docking connector, at about five-eighths of an inch, so another five-eighths deeper, give or take.
