Root any ROM via HTC's re-flashing procedure, no?

[RustyDroid]

HTC keeps the stock ROM for Aria on their site. The procedure explained. Why it won't work if try to flash the phone with any other ROM? XDA has a copy of the ATT's ROM with a couple of utils for root acceess. I like this option a lot.

Too easy to be true, right?

im sure that the rom installer checks for HTC signature before allowing a rom update.
