How to use ws-security in M2M embedded devices?

We build telemetry applications and we are looking to design a Windows CE M2M gateway.

The requirement is to make this remote device connect as a Web 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 best turnkey security scenario for 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 the Web 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

It is true that WSE is not supported on NETCF.
However some time ago one of our MVPs - Casey Chesnut did a custom port that can enable WSE on the compact framework.
See his article here:

In addition you can look up the WebServices2 namespace on the OpenNETCF site.

WSE is not supported in CF, although I heard that someone was doing a custom port at some stage.

I think that this is a really a question that the CF folks need to answer.
