If everyone knows the exchange has a fractional reserve it's not a bad thing.
If they're doing it without saying so that's another issue.

We've talked about doing something along those lines (the wallets).
I don't write the code so I'm not sure how difficult it would be to have individual wallets.
I would be interested in any solutions people can come up with though.

The system is useful because it provides transparency. The question of whether fractional reserves are desirable is not relevant.
Transparency is useful with a fractional reserve too.

E.g.
Suppose that the exchange promises to hold a minimum of 30% as a BTC reserve against all its bitcoin liabilities. Each customer is assigned a unique block explorer address that holds exactly 30% of their account balance.

If this account is not at exactly 30% of the account balance, then the customer will know that either:
a) the exchange has been hacked, or
b) the exchange is not holding a 30% BTC reserve.

Again, customers should be able to audit exchanges using block explorer. That is what the technology is there for.

Your turning an exchange into a bank, which isn't what we want, though with this you can also do what your saying as well.

Not sure if that's directed at me or cunicula. We're holding 100% and if we move away from that we'll make it very clear with enough time to pull out if you want.
Currently that isn't in the plans.
