Watching an old episode it showed the TARDIS materializing as a gate blocking a corridor (chameleon circuit was sort of working). Anyway it got me thinking could you set up the TARDIS to imitate an actual entry to somewhere without preventing it working. That is you have a locked storeroom and a TARDIS materializes over the door to it with a keyhole that will respond to two types of key's. If you use the normal storeroom key the "door" opens and you walk through it into the storeroom essentially going from an entry door here on this side of a TARDIS to an instant exit door here on the other by passing through the frame without ever actually entering the TARDIS. On the other hand if you use the actual TARDIS key then you enter into the TARDIS via whatever room you have set up as your entry way. What do people think could it work? Would it need a specific level of sophistication e.g. at least modern or at least advanced TARDIS only, a certain trait or traits e.g. scout capsule, at least one rank in systems upgrade and advanced systems or the bad trait shifting structure?
It certainly appeals to me especially since you can get it to work with different security systems. That is rather than an actual Key some of the later TARDIS models used biometric scanners and there's the "trick" feature from the doctor opening his by clicking his fingers.
You could put it pretty much anywhere there's a solid door and possibly cameras (we know the perception filter can get people to walk right by but I'm never entirely sure how it works with recorded surveilance). Either way just place it any door with a lock and bang you can come and go as you please with the perception filter backed up by the believable nature that half a dozen people just came out of a side door in a building rather than a wooden blue box that couldn't hold them. The list of options it opens up is nice as you said airport, train station or other "staff only" doors (that can be key, keycard, biometric or who know's what to differentiate access), side doors on public buildings even a simple storage space in an apartment complex if your spending some time there as a vacation or alternatively the door to a hotel suite if the TARDIS is popping you into its history line. Anyone else (maids, visitors, you with the hotel card) go into the hotel room, those with a TARDIS key however go into the TARDIS instead with the same key.
Even better it provides a nice handy plot hook for players without a timelord just insert a malfunctioning circuit . . .
"I'm telling you guy's tonight is going to be legend wait for it . . . " "Hey Barney what's the . . . wow." "Guy's I don't think this is the right party." "Lilly's right we should." clunk. WHoon Whoon "Marshal what did you hit?" "I don't know?"
one quick trip later the party is on the fifth moon of Clar Oranis trying to figure out how to get back while a time lord is muttering that they're sure they parked around here somewhere.

I tend to assume the recording glitches, covering the appearance of anything unusual and/or the Tardis adjusts its materialisation coordinates slightly so as not to be caught on camera if its appearance would be obviously out of place. This may not work perfectly every time (Bells of Saint John), but failures should be at GM discretion to make things more complicated for PCs.
"Is there a word for total screaming genius that sounds modest and a tiny bit sexy?"
I've always assumed that perception filters work by using a chaotic limiter to reduce the user's reality quotient. Basically they reduce their impact on history to the point where they don't impact anything [even people's memories].
Thus the effect transfers to film and video [and all other methods of data collection]. Which fits with the Silence being caught on camera multiple times and nobody noticing.
