Change a players skin

I'm working on a TF2 plugin for people who've requested it but don't want to use mods, just vanilla. The weapons should be easy and with 1.3 bukkit coming, texturing them is simple as well. I am just stuck on changing the skin that other players see the player as. I want a visual indication of if they're a red engineer, blue sniper, etc. Anyone know how to do this? I'm pretty sure the server sends the skins to the player, so I think it's possible.

Thanks, in advance, for your responses!

It would be impossible to do without actually changing their name as their skin comes from their name. Otherwise you would probably need Spout.

Changing their name shouldn't be a problem as displayname and name are two different variables... but then you'd need 18 minecraft accounts for the skins... blah.

That shouldn't be a problem if you set up methods to do this. All you would have to do is loop through for all players on the server.

but you can't load the skins from a file? It is forced to take them from minecraft.net?

exactly..... So therefore you would need multiple minecraft accounts with your custom skins.

raaaaaage. alright. Thanks for your responses, anyways.

It IS possible to change the color of a player's name tag. Probably not what you need though.
