Managing updates for install at a later time

[Guest]

Hi

Is there a tool that replaces/upgrades the Adept Notifier so I can choose what updates to install, and when to install them? Essentially I want updates to be installed when people are not using the machine, and/or bandwidth?

I realise that I could do this with a cron job, but that would be all or nothing, which is not always what I want.

Could the same tool, or possibly combining it with another, allow me to remotely manage several machines? So a bank of machines could, for example, get their updates at 3am.

Thanks
