Flash Intro / Video Play when click url

I have a website and have created a few videos that I would like to run, in random order, whenever someone goes to my website, before they can get to the website, sortof like a popup window with a video inside. I would call it a FlashIntro, but I'm not sure you can have that if the video chosen changes between a few different files. I do want the user to be able to click a 'skip intro' button, and a 'don't show this again' button. I also would like to be able to track how many people watch the video, forward/share it, etc, like on Vimeo or YouTube, if possible? And, I don't want it to interfere with Googles crawling of my home page. Is that possible?
