Two obvious, notable interactions:

• Ashigaru gains an unmanageable number of subrountines once this is rezzed, but is influence expensive for HB
• IQ becomes incredibly strong & great value if you rez it before using Cybernetics Court to prop up your HQ size

Arguably better than Research Station since its effect is larger & trash cost higher, though you're unlikely to want to defend this whereas RS benefits from your HQ ICE as well. Unless you're comboing with something or negating the downside of Cybernetics Division there's just not enough benefit to increased corp hand size to warrant a deck slot.

A godsend for Cerebral Imaging. Behind even one piece of taxing ICE it can be too expensive for the runner to make it worth doing anything about, and it'll save your bacon after a Siphon, especially if you have no economy in hand early.
