A medical device provides data. What does Bluetooth have to do with
anything? If the computer can reach the medical device and the medical
device can supply data this data might be fed to the app. The app has
no idea whatsoever whether this data is coming from a physical
health-o-meter, whether someone is comparing old and new results or
whether someone curious just wanted to input theoretical measures.

I fail to grasp what giving direct access to networked devices achieves.
If you've got an application that takes a video stream at runtime,
request a video stream. If that video stream happens to be linked to
/dev/cam0, /usr/vid/funny/watchme, /n/screen or /n/fifo/record is
unimportant to the application. Read in the video, do your thing. Let
the user feed you video.
This can and should apply to _all_ media types. If you've written a
contact management application, you don't want to spend time
implementing Bluetooth stuff so you can import contacts from some
wireless handheld storage devices, just for the next app writer to do
the same.
If Bluetooth becomes obsolete, everything should work the same.
Whether you use SCSI, USB, FireWire, Light Peak or Bluetooth to get
data doesn't matter. You're still working with data.
I want my contact manager to manage my contacts, not my PAN.
