I don't think it is a good idea since it makes protocol more complex. We either

1) need to pass these values as handles at all times (i.e. have this set to
true), or
2) serialize special values in strings when encoding them in JSON.

Both are a lot of work due to the following assumptions:
1) when remoteObject.type is "object", we will try to get its property names.
2) If remoteObject.type is "number", with think remoteObject.value is a number
