Is anyone using Silk?

http://www.silk-project.org/

Probably applies more to small consultancies and freelancers. I read a nice comment about it. But that was a coder talking. Considering adding it to the Software List. But not sure it’s ready to be used and useful for most people.

Comments appreciated.

is this some sort of Product Lifecycle Management software?
looks ‘interesting’.

It’s hard to truly test such an aplication without a real client in a real situation, but I think I’d have a hard time convincing trying something out which neither I nor he knows how to work.
