In my opinion, it's easier to lock down COM, such as running as
dedicated user. With XPCOM, it's even easier, as all XPCOM transport
logic is fully opensourced (and available in VBox tree),
so one can perform even more complex logic to ensure protection.
Generally, doing yet another frontend is feasible, but very time
consuming and giving no clear benefits. To get what it looks you need,
somewhat different approach is needed.
Running multiple VMs will have no problems with kernel driver, no matter
which frontend you'll use.
