The R-Pi GPU certainly supports CEC, but the closed-source Broadcom GPU driver doesn't currently surface the CEC codes to userland in order for the ARM core to gain read/write access. Maybe such support will be added later but it will only come from Broadcom/R-Pi Foundation due to the closed nature of the driver (Broadcom have, apparently, demonstrated CEC working with their GPUs).
If/when the GPU driver supports CEC, then perhaps it can be supported by XBMC.

According to the hdmi.org
link provided previously, 55mA is the minimum
provided on the 5V line which is pretty much useless in terms of powering most devices, and since there is no set standard for negotiating or acquiring a higher current (which may or may not be available) it seems highly unlikely that this is a useful avenue for anything practical as the chances of it actually working (ie. enough current available between two random devices) is so low.
As it is, the R-Pi requires [email protected]
to operate, so it won't even be possible to power the board from a single USB port, though it may be possible using two powered USB ports and a Y-cable.
