Usually you only want to do that over a VPN. Most NetBIOS traffic is generated by broadcasts, which are not routable anyway.

Only if you want windows print and file sharing (e.g. with the ability to 'browse' to the share) functional to/from outside your LAN (i.e. without using a VPN).
And I think some devices (e.g. webcams) use netbios to talk to their controlling apps... but I would think that traffic could be channeled through a VPN, also.

No there isn't, because NetBIOS isn't a routable protocol... So technically speaking you can't "let NetBIOS out of your network." However, as has been mentioned, using a VPN is a way to get it out of your physical location... but it's still technically on your network.
