I agree with you that maybe this proposal is vague for a GSoC, but I don't think that websockets is a good option either, because not all browsers support them. Indeed, web development has gone a long way without contant communication with the server and I think Haskell should support this way of working too.
My idea would rather go on the direction of using stablished Haskell concepts to web development. Some ideas are: - use an applicative interface like the one of Yesod for forms validation and sending - see the DOM via a Zipper interface, so widgets will "anchor" themselves in some point of the tree and change things around them - use FRP for Canvas interaction - ... Actually, thinking which Haskell concepts could behave well with client-side development is an interesting discussion by its own :) 2012/3/7 Greg Weber <g...@gregweber.info> > This is obviously a great concept.
