Pelle Braendgaard just launched and announced a new free Rails service entitled SoapBX that let’s you use a combination of Textile and S5 to forget about Powerpoint and Keynote:

About the development of SoapBX using Rails, Pelle writes:

I got an idea less than two weeks ago and now as a testament to the
power of Rails I have released the first initial beta version of
SoapBx, with less than 20 hours of programming involved so far.

Congratulations on the launch, Pelle!
