Can We Have shared Isolate File so that all the application in the device can share the Global Data.Instead of keeping the same data in each isolated storage file for each app.This Feature may reduce replication of data.

Even so it is a good idea I am afraid that MS will not do it. We're "forced" to use SkyDrive, DropBox etc. for sharing data between apps.
I like the idea very much!
