I have been very interested in the Flex solution. Mostly because it supports 
both desktops and the web. I use Dabo for my UI solution and found it covers 
most everything I need at the moment.   But I have real concerns regarding 
data access using Flex.

Flex is asynchronous and most desktop data app's are synchronous when it comes 
to accessing data.  All I have been doing is reading about Flex so maybe 
there is a solution I am not aware of.  It sounds like you are working with 
Flex - is there a solution?
