Interestingly enough yesterday my friend & I devised a similar idea
where we setup two ST instances per format, (call them A and B,) each
set as a fallback for the other. We then setup a cronjob to restart
A, then B, then A etc on an alternating schedule, so our listeners get
moved from A->B->A on a regular interval. Quite a hack but at least
our stream is usable for now.

Good tip there, I'll give that a try, thanks!
