A couple of suggestions for the future...

Directory Sync between two users
(Standard feature of unix since the late 70's and still very usefull today)
This could be a case of sharing the directory
An automated download capability to defined users

The biggest problem with shared applications between users over the internet is the problem of interconnect between two computers behind NAT's. Skype has implemented a solution that keep most commuincations to the direct path and now we need shared functionality as if we were on the same sub net...

VPN function to allow services to run between users - a simple way to allow a lot of products to share the Skype service. While the skpye solution may be best for bandwidth management (QoS) and system control.. this does allow for easy expansion oif the platform service..

Desktop Share function for helping othersand remote control

H 264 Video sharing and conferencing

thanks for great poroduct
