Depends on what was compromised in the framework for the hacked rom. Droid and Cliq to name two have not been hacked- Android team and Motorola took steps to make it more difficult.

For now and maybe "for ever", could be stuck with official versions for most devices. This especially will be an issue as hardware becomes more fragmented and Android hackers become more spread out.

Best bet is to buy an HTC device (not the 7201 chipset ones now) next year, since then you would have XDA forum community on your side to make roms. They only deal with HTC devices.
