Since I wrote that I've also ported over some of my other greasemonkey scripts. I still need to polish them up a lot but they're working and that's cool. I'm looking forward to playing with settings pages and auto updates and what not.
I also made a Makefile (my first in about 7 years) to make the .crx file automatically using a python program I found on the intertubes (and modified slightly)
I'm mostly using the dev channel Chrome on Linux and Mac and they just added extensions support, it's really nice and is now my primary browser.
