Sure, but a more capable processor doesn't hurt when you're prototyping
or doing a small run. If an ASIC can do it, it's trivial in ARM assembly.

Actually, 802.3af does work over GigE. Cisco sells line cards for it.
Only problem would be dealing with the drive's startup current, but
supercapacitors could cover it. I haven't the faintest idea what it'd
be useful for but it's doable nonetheless.
