I have a history of taking on giants head on. Even I thought on so many occasions that what I was doing is insane and will never work, lo and behold, it did.

Currently I am building a simplified windows deployment system (fdeploy.com) which already exists but is no longer available freely. I want to change that.

My advice is: yes, do it. Give it a try, with most essential features and do not get lost in the details.

Deliver something and see if people want it. Anything. The sooner the better.
