Check out this link to the wap11 manual.
ftp://ftp.linksys.com/pdf/wap11ug.pdfOn page 24 of the manual (not the pdf) it talks about a wireless bridge. I think that is what you're looking for.
I guess all you need is one of these and a 4 port hub behind your HT. Then you can plug in your IR1000, X-Box, and your Replay TV.
