Actually, they can be downloaded, as .rm files. If you open one of the .ram files on thislife.org, it references www.wbez.org/ta/XXX.ra, where XXX is the episode number. Change the XXX to the number of the episode you want to download, and hey presto! Real Audio downloadable file. They're reasonably large-sized files, one I looked at was ~49MB.

Hope this helps! :-)
