How do I use my wireless remote and my speedlite on my Canon XSi when they both require the hot shoe?

I am buying an Adorama Wireless Radio Remote for my Canon XSi and I want to know if it's possible to use it with my speedlite. I would think they both have to use the hot shoe so Im not sure how this would be possible. Will I be unable to use the flash when using the remote? Thanks for any help.
