Brainstorming
I'd like to introduce a concept of a new feature called Account Control. This feature will allow to do different things with ur accounts. For example, u will be able to set a lock on an account to prohibit any outgoing transactions until a special condition met (e.g. an incoming transaction from a predefined account). Another example is Pooled Forging, when an account leases its forging power to another account.
Please, post here what u would like to see in Account Control.
I'd like to see spending limits. For example so that I could only spend a maximum of 100 NXT/day from an account. Trying to steal this account would be less profitable.
