The crux of the matter, in my opinion, boils down to a couple of things.

1) Creating a wire-format that works with other languages is a much bigger
undertaking, and one that would need to be integrated into Qt itself, not
QtRO.  Based on the (lack of) response from others, it seems this is not
a palatable change at this time.

2) A Qt-to-Qt distributed object system can provide a rich set of features
leveraging Qt’s existing capabilities, without requiring a lot of additional
code by the user.  Such a system doesn’t currently exist in Qt, would
provide value, and thus the request to move QtRO out of the playground.
*yet another* isn’t relevant unless you want to delve back into the wire-
format side of this discussion (#1).

For providing Qt new functionality, I feel the existing QtRO design is sound.
If at some point #1 becomes a reality, I would be glad to revisit a generic
idl.
