Equivalent of -webkit-text-stroke for FF and IE

I saw somewhere that the style -webkit-text-stroke is not supported by any version of FF (or IE, for that matter but the last one is hardly a surprise). What can i do about it if i need to allow my Mozilla/Microsoft powered visitors to see the outlining.

I have the following solutions, none of which feels very right.

1. Forget about it and let people choose a better browser.
2. Join the Mozilla team and get employment at Microsoft to speed up the develpment
3. Use images for outlining and let Paint.NET do the job.
4. Wait until somebody else does something appropriate about that.

Suggestions?
