Recording is possible.

Replay in Xnee is done via XTest, so only device events are possible to
replay.

"Replaying" of non device events wouldn't make much sense though. All
non device events are results of the device events (well. not entirely
true). When you click a button you ask X to do something via the APIs.
It could be to show a picture. Then when the X server is done doing this
it sends an event to the client to tell that it's ready. What good would
it be to fake this event ... without having actually shown the picture.
Faking all requests (sent by the client, via the X APIs) would be
possible to implement but time consuming.

Then you better look at tools such as istanbul or recordmydesktop.

No, there is not.

You probably have to implement a new X server or extension to do this.

Read the Xnee manual, check "7.4.3 Replay", for info about the file


But please, feel free to ask questions on the public mailing lists :)
