Pressure sensitive stylus for Nexus 7

Has anyone heard of pressure-sensitivity being added to the Nexus 7 version of Touch? I know there's programs that already use pressure-sensitivity from the touchpad, like the Markers app. When I saw the Stylus options, I thought this had been included. I mean, I work with Nexus 7s as my job right now and one of the reasons I bought one was because it had something like 300 pts of pressure sensitivity.

I did have a weird experience where it seem to detect pressure at one point and tapered a line but never was able to replicate it.

Also, I would also like to do a trick I saw somewhere on a Nexus where you could create straight lines and curves by putting down two or more fingers, and releasing the first finger creates a line from that point to the last finger.
