Then, you have to worry about syncing them. For example, if the setup changes on the phone while NOT connected, then 'dongle' may send data that the 'host' doesn't understand. Just more stuff to consider when trying to implement this.
I think space shouldn't be a problem even without compression. Unless you want to log a full day's worth of data. That then becomes an analysis problem. Too much data to parse by a human.
