Hi Everyone,  
I like client tag change event scripts. Has anyone ever run into an issue where you only wanted certain clients to react to a tag change event script? Or is it bad design to make client tag change events client specific?

It's reasonable. Simply put your filtering logic in the beginning and return early. (Presumably the event is a one-liner delegating to a project library function. If not, make it so.)

Can I simply filter by client hostname?

I would think you can filter by anything you like.
