Node without gateway

Is it possible to run a node without the gateway, during betanet? or will this only be possible on mainnet?

Surely it won’t be possible on the mainnet, because the gateway will be the only point of access to the node.

I don’t know if it’s technically possible for the betanet, but given the low requirements of the gateway you could run it on the same machine of the node.
