I'll admit we maybe missed a little on London Library :P. Though I don't see why library hardware would be any better than dorm computers for running, or why using the library machines would make your normally very costly femme fatale free??
The issue I have with Beach Party is that trying to model hand size as some kind of connection based mechanic seems dodgy at best when you take into account all the other effects that interact with the hand.
As far as cards that only interact with the Runners hand size, they all are either brain-related (Mental Health Clinic) or are things that directly augment your rig/interface in some way. I've seen Public Sympathy mentioned in support of Beach Party, but the flavour there pretty clearly indicates that Kate is undergoing some medical therapy thanks to public donations (and so having this trashed cuts off her funding and thus her continued therapy).
Chairman Hiro and Bagbiter are the ones I'm struggling to explain with this model. But the rest fit.
