This is great. However, do you think it might be useful to add some more information regarding the usability status? For example, the MIUI and AOSP ROMs aren't fully-functional, so perhaps a note stating that they're in development or alpha stage? Granted, someone can figure that out by going to the thread and reading, but it might be helpful nonetheless. I know some others have mentioned this and the OP also clarified a bit, but it would hopefully prevent any confusion.
Thanks for putting this together. Let me know if you need help maintaining this going forward as it will likely become a bit more time consuming as more ROMs come out.
