For all y'all who use (by choice or not) in-ear systems:  Have you ever heard of, or seen, some type of limiter that can be used between the in-ear signal (such as an Aviom) and the earphones that will prevent spikes from getting through?
 
I am having significant issues with this lately.  The spikes can be from a specific channel in the mix or, as today, from someone unplugging a condenser mic without muting the line first.
 
I would absolutely love to have something between me and the Aviom mixer that would prevent anything from exceeding X decibels getting to my ears.
 
I've been using hearing protection for years and have custom earpieces to isolate myself from the 90+ decibels of on stage volume.  But all of that is worthless if someone else can jack the volume of a system that is directly in my ear.
 
Thanks for any leads you know of.

Thanks for asking, wayne.  I've been wondering about this as well and I've been too lazy to look into it myself.   I've been contemplating in-ears for a while and this has always been a concern of mine.
 
Sorry to not add anything useful other than letting you know you're not alone in this pondering thought.  Or something along those lines.
