I was wondering if you could just use blink::WebBluetoothDevice directly (but I
think I've convinced myself that wouldn't be worth it).
The problems would be the WebVector<WebString>, and probably even the WebString
instances themseves.

ViewHostMsg_CreateWindow has a similar struct and gets around this (with its
blink::WebWindowFeatures struct) by passing the WebWindowFeatures struct minus
its WebVector field, and separately passing the vector as a
std::vector<base::string16>, and then merging it back together in the browser
process (see
https://code.google.com/p/chromium/codesearch#chromium/src/content/common/vie...
and
https://code.google.com/p/chromium/codesearch#chromium/src/content/browser/re...)

Yes, the strings and vectors are a major issue, also now DEPS are set to prevent
this type of sharing. I had a brief chat with jam@ about that and it seems the
duplication is favored.

+  BluetoothDevice();
+  BluetoothDevice(const std::string& instance_id,
+                  const base::string16& name_in,

[Marijn Kruisselbrink, 2015/01/28 21:45:56]

why name_in and not just name?

[scheib, 2015/01/28 22:23:55]

Done.
