You could try hacking in the Longhorn DLL's, however I think that may not work either, plus you run the risk of breaking your extender support.
The extenders do use RDP technology for there drawing etc, but it is slightly different from standard RDP. The extender needs to have the abilities to render all of the functions the MCE PC sends to it (basically they borrowed the extended RDP stuff from MCE for Vista so Glass etc could be used over TS, and in theory DX10 apps as well) as there is not screen scraping involved at all
It would be ace to have a sw extender, I know MS use them internaly (so it is possible) for testing, they however never released it because of agreements with Linksys etc as it would devalue the extenders they sold. I'm not sure why they will not release it now however, because after all, how many people who want an extender will not just buy a 360? they are cheaper than Linksys's offering anyhow.
It's a pitty that the extender technology never made it into Vista, however if your good at decoding stuff the software that the 360 runs is on all MCE enabled versions of Vista it's located in C:\windows\eHome\MCX\X02
