I was just thinking that in general most non-ui libraries should be able to be ported to FlexJS quite easily. One I found particularly interesting recently was FlexORM (Some sort of JPA for Flex). I am using this and would love to have that in the Browser. As Browsers do support sqlite databases the same way AIR does, I think it should be quite easy to provide this to FlexJS. What do you think?
Here's a small link to how to use the SQLite db in JavaScript http://www.html5rocks.com/en/tutorials/webdatabase/todo/ Chris
