a plugin/extension for multiple mouses on screen and "inputers"

[Alen Pecanin]

Hey guys,

This will maybe be a weird thing. But is there a plugin or extension one can download for a browser to enable multiple "inputers" a the same time? Lets say there is an online test in a browser, and you and 4 other friends connect with 4 different wireless keyboards, or wired for that sake, and 4 different mouses, and there is an online test where time counts, and in total 5 people write and finish off that test at the same time, instead of 1 guy typing it all to save time? Is there a plugin for this?
It would be fun if you could finish off a test that takes for example 10 minutes and lets say 700 words + quiz, in 2 minutes total with all answers written correctly and in detail. Of course main monitor would be 21:9 ratio and rotated, so you can see the whole test at once and go ham on it
