Yep, Altuit (my company) owns Hemingway. You're more than welcome to take it for a spin. Check out the links above to the documentation, also the Hemingway Client has direct links in it to docs as well. Hemingway is configured by us as an ASP, which means you have to use it with our servers. Purchasing a license for 1-domain, unlimited webs is $480 per year. To license the server software is more.
