There is no specific reason to use 0.6.5, its just that I found it to be the latest release. If you suggest that 0.7 would be more suitable for embedded system, then I will try 0.7 instead.

I just want to use the NM daemon, assuming that it would be enough of automatic network configuration. I would be using it on a single user embedded Linux device, no use case of multiuser. In this case, still do I need the gnome applet? More over I would not have Gnome environment on the device nor I would have GTK.

But I would like to have the authentication mechanism for the wireless, atleast WEP and WPA to begin with.
With this use case scenario, can you please tell me if I can use the Network Manager and by excluding and including which components in configuration? Do I also need some kind of Keyring Manager? Which one would be suitable if I don't have Gnome?

In a reply to my previous post someone pointed out that I would also need a cryptographic library. Can I avoid the functionality that needs the cryptographic libraries, to begin with. I do have OpenSSL on my device but dont have GNU TLS or Mozillaa NSS. Did you guys find GNU TLS and Mozialla NSS to be better than OpenSSL?

Thanks for all your valuable inputs,
