#1. The blood on the toris can't hurt as an option. One workaround for it is to just put it on your textures, but an option should be fine.

#2. I have always liked the idea of more interaction in the queue. It sometimes gets boring while sitting in the queue. Most of the time, people don't want to listen to toris ripping eachother's heads off while surfing the web, so they have their sound off and sometimes miss their turn. This idea is cool, and I like it.

#3. I don't really like to use older clients because I feel out of date, but it can't hurt.

#4. This idea is my favorite. I once saw an idea like an intro video that you can insert to sort of introduce your character that is like 5 seconds long. Things like these would add even another thing to the market and video makers will have more opportunities to make money instead of just artists.
