The ideal switcher (- designed by a camel?)

What are the features you like best about various switchers? Imagine all the good bits assembled into a single product; what would it look like?
I'll start the ball rolling with some of my favourites.
CLEAN FEED capabilities.
The Snell and Willcox Kahuna allows you to specify what background is seen on any of four outputs, and which keys are visible. The cool part is that you can specify individual Backgrounds (such as A, B, Utility1 or Utility2), or Transitions (such as the A/B transition, or the U1/U2 transition). You can also specify "no" background, which gives just the keys over Black. You specify any, all or none of the keys on any output. This approach makes it simple to allow one M/E to generate four simple "key + bg" composites. It also allows a "Partially-Split M/E" mode where a keyer can be shared between partitions.
RE ENTRY capabilities.
The Snell and Willcox Kahuna allows any M/E output to be re-entered as a source on to any M/E, including the originating M/E.
PC Control
The Thomson Kalypso allows a regular PC to be used as a Menu PC control. Many features including crosspoint selection can be achieved from the Menu.
INTERNAL/EXTERNAL EFFECTS SEND
The Thomson Kalypso "Classic" could take the source from a Keyer bus, re-direct it through either an Internal DVE or an External DVE (to provide some kind of 3-D manipulation), and bring it back into the keyer seamlessly.
INTERNAL DPM
The Thomson Zodiak has a DPM channel in every keyer. If you had sixteen keyers, you'd have sixteen DPM channels.
PRIMARY CROSSPOINT DPM
The Sony MVS8000 allows the DPM to be used as a Source on a background crosspoint. So if the DPM is providing aspect-ratio-conversion, you don't need to use a keyer.
MULTIPLE BUS LINKING
The Sony MVS8000 allows a buss to control multiple destination busses. So your main program cut can provide a different "mix-minus" to different aux busses (a wide-shot camera not being fed to a projection screen, or a sideline commentator not being seen on a client's feed).
Feel free to add your own favourites to the list.
