unity web hosting

Hi I have a few small games I want to set up with the web player so my friends who are helping me can check them out. what I’m looking for is a website the supports the .unity file types needed to use the web player but I can password protect the page that you access the html files from so only people I give the password to can access the page and then use the web player, what sites do it or do I need to buy my own domain and code it to do this any help would be great thanks

The webplayer is a plugin (just like flash), so your server just needs to be any old server capable of showing web pages.

All the rest of your questions are best answered by your web host.
