Sounds like your solution would work for me as well. I hadn't thought of
using vnc and related tools.

I'm not sure what kind of integration makes sense, if any.

A record/playback feature could be

1) In QEMU proper wedged between the QEMU and the guest, hooked into the
data traffic
2) In a front end to QEMU which just communicates through a
to-be-implemented API; basically still #1 just architecturally different
3) In a completely separate utility that knows nothing about QEMU and
just deals with X. Such utilities exist for X
4) In a VNC viewer
5) In the guest only; such utilities exist for Windows and probably some
other OSes.

Not sure what the pros/cons are exactly. (5) can be ruled out since you
wouldn't be able to script at the QEMU level (saving/loading system
state images and such, and not all OSes necessarily have good utilities
for recording and playing back such events.
