I wouldn't be so negative about it being 'yet another clone'. You've created a product that fulfils a need. The fact that others have produced similar products demonstrates there is a viable market. You've targeted a specific need with the download option which presumably you see as under served. I tried the web demo but as others have mentioned it's not working at the moment. I do have some comments on the website itself. I find the homepage a little confusing. Clicking 'Home' take me to 'Wireframe and Mockups', which is actually the homepage. I'd move 'About' and 'blog' links to the end of the nav, as they are less important to a potential customer. The features and benefits can probably do without the shaded background - use a larger heading and they will stand out on their own, while reducing clutter. I'm interested to see how the 'portable server' approach goes. I can see the appeal of self-hosting options for larger companies, but I suspect the personal users will be less technical, business types who don't want to worry about a local web server. Hosting the app for them will cut down on your support requests, so why not sell online access to personal users for $77 and the enterprise, self-hosted package for more (say, $299)?
