Are there any other series like this?

The series doesn't have to be Quantum Leap based. Just if you know of any other virtual series out there that are audio based please let me know. Also some thing I think people would like to know. From the Ashes will be giving out awards for best virtual series 2007. I've already placed a vote for a QL based series, but I'm not going to name which one.
Ah. Cool. Thanks for letting us know.

I thought that you were just looking for Quantum Leap type audios. The following places are two places that have audios:

Both of these places are really good at what they do, in my opinion. Take a look and see what you think.

Drealm Realm Enterprises:

Darker Projects:

I don't know any other audio places that have been working on ongoing story lines.
