Playing offline

Hello,
I was wondering if it is possible to play Eastern Front in off line mode?  I am not always connected to the internet but would still like to play single player.  Are there any any command line parameters that can be typed in under the advanced section of the launcher that would enable offline play?  If not could the developers consider enabling the mod to support off line play?
Thanks

I guess you would need to put steam in off line mode to achieve such thing.

Yes, and it works, i have just tried it.  ;)
