Greg, it is about several MB data and may be more. Anyhow, no matter how geat the talk is. We need a practical solution at current moment, not in future. As a result, we're now building a prototype to prove the concept in both product and see whether it solves my users problems. For Silverlight, our progress is slow since it doesn't support bi-directinal editing in this beta version (Coding makes visual object changes but it doesn't allow the reverse case). This is also our hesitation on Silverlight. Though i believe that Microsoft is a good copier and will use all his effort to penetrate the market. However, we can't tell management that we use beta product to develop application. Customer wants solution only. We can't wait too long. Anyhow, we still test it. For flex, it is better. just thinking how to resolve the use case upon my previous posted problem. Since there is limitation on sharedobject, I will try to re-design the whole architecture and see whether it fits the requirement i.e. put limited information on desktop. But, 100KB may not be enough. (I have tried the sync by using AIR It's great if it is in browser !)
