Rolling releases are good idea. FreeBSD ports are outdated. There is sometimes year old ports.
I tried first rolling release iso but noticed that vmware video and vmmouse drivers are still outdated. Could you update xf86-video-vmware to 13.0.0 version and vmmouse to the same version.
There are newer vmware video and vmmouse drivers :
(can be compiled with make or gmake (both work))
(only gmake work(make and make install produce errors))
I compiled newer version of those myself and new vmware video is faster than old one. Currently pkgng and ports only include vmware video and vmmouse that are at the version 12.0.2_1. Those are outdated and old vmmouse doesn't work properly with newer PC-BSD versions. And also vmware tools kernel drivers compiling isn't working it is complaining missing freebsd kernel source. I did fetch system sources but it only fetched them up to freebsd 9 not 9.1. PC-BSD 9.1 stable vmware tools kernel drivers compile fine and don't complain missing kernel source.
