If you create a real ALDL data bus you can have 3 devices on it, but usually while logging the logging device will tell everything else to stop talking while it logs. To have this work you'd need to get technical and design adx files where one polls the pcm and the other one listens passively and extracts the needed data. I'd leave ALDLDroid to run the logging and look to have a modified adx on the pc that does not request data and instead just picks up the responses as it sees them. Ive not done this but I think it'd be a change to the connect macro to just make it start and remove or change the poll macro to remove that transmit part, and I think the receive part would just work as it sees the data. Not sure if it'd need something to ignore the data request packets and only attempt to decode the responses.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396
