Hi. After a long time away from PD, I come crawling back :-)

I'm hoping to start doing a podcast using my Linux system, and, after digging around in search of something akin to the CastBlaster currently under beta for Windows, it strikes me that it might make sense to put the pieces together under PD. (There's a good Flash movie in which someone walks through using the CastBlaster at http://mp3.dailysourcecode.podshow.com/cbswf/testcastblaster.html )

Before I reinvent the wheel: is anyone else doing this?
