I forgot to run an IR blaster wire

So, I posted earlier about finishing my basement and running wires...well, I forgot to run the wire that you stick in front of the TV and then run to the closet and it relays the IR signal to all the components. What are my options for doing this wirelessly?

I found a unit that looks like you replace a battery in the remote and then stick another unit in the closet that seems like it would work - but before I buy, is this my best option? BAsically it converts IR to RF and then back to IR LINK

Is there anything that uses wifi? IR to wifi to IR? Other options?

Thanks guys.
