Thanks all. I ordered a pair of WBR-G54 today. I'll have one act as a base station and then bridge the second to it. I was able to confirm that some people over on AVSForum have used these units successfully to do exactly what I want. These where one of only two 11g solutions (the other is a pair of linksys access points bridged, but they can't be base stations at the same time) that appeared to definitely work for streaming with ReplayTVs.
