By this you mean the uid the process is running as and not the actual
'qemu' uid, right? Just making sure..
No, I mean that libguestfs is unable to open the disk in anything
other than read-only mode. The 'qemu' user/uid has nothing to do with
this.

Hmm, ok. I will keep plugging away and update the thread if I discover
something.
One thing that's curious is I've also played with just using
command-line `virt-X` and `guestfish` to upload new files to the same
images and haven't had the same write problems and/or process hangs.
Secondly, the changes *do* get written to the images so it's certainly
not a flat-out permission denied issue.
It's got something to do with what permissions or user your daemon /
remote process runs as, but from here it's hard to say exactly what.
