I have a fair bit of experience using FreeBSD as a host and a guest
within VMWare and was pretty happy with it. The methodology you describe
is pretty standard fare, unless you're developing code as a kernel
module, and manage to keep out bugs that would cause instability during
the development process... that can definitely cut down development
time.
