Not sure if serious but... I speculated about this in another thread. Based on what I have seen from regular sequential turbos (Supra, Rx-7, Legacy) and twin charged engines (VW), it could work like this:

Basically the electrically driven compressor (electric turbo, whatever you want to call it) will supply boost at the lower rpm range and a butterfly valve will separate its air from the two actual turbos. The exhaust will spool up the two turbos and a relief valve (kinda like a blowoff valve) will be open while they come up to speed. Then when it's time for the twin turbos to come online, the butterfly valve will open, the relief valve will close, and the electric compressor may be de-clutched.
