I have a bit of experience with script code, and it actually is quite possible to achieve it. I'm just not sure how willing the DM's would be willing to go to do it. It could work almost like the bottom left chat ticks, but slightly different. Like whenever you go to a translation site for an actual language. For instance. If you go to a English/spanish translation site, you can have it translate either way. You tick spanish to english. Type in something like. (Mucho grande gato rojo en me pantalones azul!) and it automatically translates to the other side of the page, (There is a very big red cat in my blue pants.) ((Didn't actually translate on a site, savvy with spanish.

Just an example.)) It could be integrated into the normal chat box, instead of at the top of the screen, and it could be done with a number of ways. The thing is though, how many lines of code, changes, bugs, and other factors would affect such a thing, or if the DM's even deem it something that would benefit the server overall.
