ATV as a wifi bridge?

I’m not sure if this is possible, but a feature I’d love(and I’m sure many others would as well) would be to use the atv as a wifi bridge/extender.

Most new tvs/blue ray players have internet capabilities, but not all have built in wireless adapters, and most of the adapters are quite expensive.

One workaround is buying a wireless extender, kindof like a wireless to wired adapter.

If the apple tv could do this it would be great.
