Right....but there's a difference between multitasking and multiple remotes communicating on the same frequency at the same time. I'm certainly not an expert, but the same remotes can/are being used for the xp8s as were used for the rp6s. Therefore same frequency. So if someone is ramping up volume for example....no one else in the house is going to be able to talk on the same frequency while the volume button is being held down on the other remote. Now, that being said....if you trigger a system macro that runs for 5-10 seconds, you should certainly be able to trigger something else during this time from another remote as long as the xp8 can multitask both macros.
