In Flex 1.5 there is not. However Flex 2.0 will include the "Enterprise Data Services" which include exactly this functionality. This was demonstrated at MAX last fall and Adobe has presented several web casts on it. As you note (and much like other existing client/server products like PowerBuilder) the data services will include the ability to track "changed" or "dirty" data on the client, marshal those changes to the server, and will provide for a pluggable persistence layer which will handle writing the changes in an optimized way to the underlying data store. This will include things like optimistic updates, etc.
