Sub Account Availability ?

Hello,
I sent a message to support on availability of 'Sub Accounts'. Was looking for a way to give kids remote access to record/view while away at school. Local cable provider allows this. Was instructed to submit enhancement. Does anyone know if this is actually available, and i missed it ? Would rather not give user/pwd (with billing, etc information), but just an account so they can
watch remotely.

Thanks,
Steve
