Lazyweb Request: An RIA Wireframing Service

Something just struck me–something that I’d really like to have. Can someone create an RIA that allows me to quickly create a low-fidelity sketch of a site, along with a service that allows these to be published, annotated, and shared online? Off the cuff, my base requirements for this would be:

• Multiple pages, with the ability to onion-skin them.
• Basic tools: shapes, lines, text. Of course, they need to remain editable constantly and, oh what the heck, allow me to push and pull them in front of one another.
• Online publishing — something like “share this site”
• Hyperlinks between pages
• Multiple authors and reviewers
• Secure login
• Site tree navigator
• Annotations, like callouts and speech bubbles
• Collapsible notes pane

Some really nice-to-have’s include:

• Multiple sites, with reusable components across them
• Multiple master pages
• A desktop client that can sync up to the site
• Versioning
• Export site to PDF

Maybe there’s something already out there that does the task? Adobe Version Cue has some collaboration tools that I haven’t yet explored. Gliffy does some of this too. Denim is close, but lacks a service to map up to.

Some of the tools that I think do a great job, and would serve as inspiration for this tool include:

• Skitch, because it seamlessly posts images to the web
• Gliffy, for its versioning, collaboration and nice drawing tools

Finally, while I’m at it (and since there’s still lots of time before Christmas), I want a image thumbnail web service. Basically, I send it an image and tell it what size and type of thumbnails I want. Perhaps I even supply it with the crop coordinates. It sends me back a gzipped file with my images. Oh I can wish.
