Re: Help: Development of large App with GWT

With ability to bid on multiple bidding at the same time I think what you are leveraging is the ability to do multiple AJAX calls to server simultaneously which is GWT strength but is not unique to GWT. There are many AJAX engines out there. I feel where GWT stands out is to able to push a lot of
