A colleague of mine got Internet sharing working with this ROM. Ironically, all he did was get an older version of the Internet Sharing files, and copy them into the Windows directory using Total Commander. Presto! No hanging animation.
Here's one example over from XDA:

By the way -- I'm really impressed with this ROM. The only thing I'm still figuring out is getting the notification and phone settings to stick, without registry editing. When we hit "OK," the sounds/notifications and phone setting windows don't exit, and don't seem to like saving the settings. Nonetheless, lookin' good!
