FYI, I already did fake multitouch thingie to N810 few years back when we were playing with webkit multitouch API's on single touch devices. AFAIK same code works in N900.
I tried "multitouch" on ubuntu with two attached mice a couple of years ago and it seemed to work ok. There was not so much support back then from applications, but you could drag two windows simultaneously. I also asked on the N9 anticipation thread and somebody pointed out that harmattan uses a normal X server. So why are we talking about X server an multitouch when it already works? Is the maemo X server so outdated?

But the main cause is to have it intuitive. It's not nice to move the finger from the center while still pressing the key :P
