We are working on a solution where exchanges can set daily rate limits on withdraw activity from their account. Their "warm storage account" could be online allowing them to withdraw X% per day to their "hot storage account".
The downside from a user's perspective is that attempts to withdraw your funds would be rate limited by the same algorithm. But at least it would be transparent why there is a delay in withdrawal.
This is really good to hear, but I'd still hope to see a third-tier cold storage with manual offline transactions to refill the hot/warm wallets. Forgive me if there's already a method, but are offline signing tools on the to-do list anywhere, by the way?

A possible solution would be to add 2 factor authorization. This would be great for users and exchanges could move a majority of funds to an account secured by a secondary hardware PIN.

As long as the default is hot storage and people have to opt in for warm storage (much like Coinbase does there vault), I think this would be a great feature to add.

Maybe the limit could be increased substantially for people that have 2fa?

Still 2FA is better. This makes very little sense. Security should come first.
