That sounds possible. I guess you'd only have to preload a few
of the low level libraries which collect keyboard/mouse events.
However,
a) I'm not sure if you can do this under Win32
b) some systems require that you have root privileges to do this
so it's probably not a general purpose solution.

I can install an event filter on app2 that only reads (not consume) events.
For each event, the event filter can compose a QString with event info and
send it using TCP com to app1.
Then, I can send this QString (in the other way, from app1 to app2) to an
object resident int app2 who will create the appropiate event to run the
action saved before.

With event filters, it is not neccesary.
