[Interest] Data Distribution Service as a new Qt IPC?

[Miller, Doug]

I've seen two proprietary Qt wrappers for DDS, but the one I saw online before I can't seem to find now.  The proprietary wrappers were achieved with modest effort.  The point is that there is interest in such a wrapper and that an open sourced version could be easily obtained.  DDS has a spec (just like DBus) from which a wrapper could be built that would position it to work with any vendor's DDS c++ implementation.

I'd be very interested to see this as well, and to contribute when possible. I'm currently working on a project with multiple processes communicating lots & lots of data over a network via DDS.

Doug, you mentioned having seen Qt wrappers for DDS in past. Are these internal to where you work, or could they be found online?

Thanks,

I did not see the discussion of Replicant before.  Seems like they would like DDS as well.   Actually I would like to see the Qt Service Framework restored  to the core and have DDS implemented as a transport mechanism in addition to QLocalSocket and DBus. This way applications are written using standard Qt,  but can be deployed using tranport mechanisms appropriate for the use case at hand.

If you have intention to do that, go ahead and request the repository.

Note also the discussions about Replicant about a month and a half ago.
