Does anyone else use this service that could answer me a few questions?

1. How does this service get the email and data? It looks like the software runs on the desktop and pulls the data from exchange/shared folders. Where does it then send the data to? Directly to the phone, or is there a middle-man that relays the traffic?

2. What type of security is enabled between this conneciton? I saw key generation, and I'm guessing there is some type of encryption, but what exactly?

I'm considering this as an option for some employees use, but I question the security of the data being transmitted/relayed to the treo.

Any information is helpful, and if there's a link to this information here or at sprint, I'd love to see it.
