Haha! My friend, it's bundled in with Unofficial piKey 0.5

In Unofficial piKey 0.5, I've created a version of PSPSWrite with key repeats and the latest drivers.

Moreover, I've added a few lines in the 0.5 release so that if a ZX-81 aplication is detected it automatilcy exits the piKey thread, meaning that it won't freeze anymore.

Have fun!
