I have tracked down SME from older sites where it made big claims.  I need to know if it can do the following under this free version, or to give up on this idea:
gateway content filter - squidguard
gateway virus protection
Samba file/print w/ Windows machines (roaming profiles if possible)
I have read the other things it can do, but wasn't sure about these things.  If anyone can fill me in that would be wonderful.  That way I would know to pursue or not.
Thanks!
