Ok... In the company I used to work for we started using Atlassian Confluence for all our documentation purposes. Two plugins - Balsamiq Mockups and Gliffy really helped the adoption process of the whole ecosystem. Your product looks nice, but here are two features that made Gliffy stand out (yes I am aware that the use case is different since one is a plug in and the other is a standalone product), references between diagrams - on one page you would lay out general architecture and comment on it, then on subpages you would work out the details. Gliffy allows the generated inline diagram to link to other pages/diagrams via generated imagemap. Another is UML support - yes UML sucks, but comes handy now and then. And there is one more "feature" request that EVERYBODY working on this kind of tooling forgets about. When you draw a complex diagram, line connectors form spaghetti nightmare - its hard to see what goes where. So there would be two options - create loops where wire is passing over a wire (like in EC diagrams) or you could introduce nodes that would be used when wires are supposed to form a crossed node. So my advice would be look into integrating this thing into some existing frameworks/extensible products.
