How to use ws-security in M2M embedded devices?

The requirement is to make this remote device connect as aWeb Service Client, but it needs to be secure.

Is WSE (2.0 or 3.0) supported in CE? are the tools and wizards available?

What should be the bestturnkey security scenariofor remote CE devices that connect over Ethernet, Dial-up or even GPRS/CDMA?

The devices are known and might have windows accounts (User name/Password) but we are not sure if itis extra overhead to maintain, or does it makes life easier...

Note: For theWeb Service Server we are looking at a .Net NOC with SQL, & Windows 2003 .Net servers.

The goal is to have many (1000s) gateways performing remote readings and reporting back to the server.

I am looking for links, suggestions, warnings, gotchas, etc...
Thx,
Uri
