Requiring administrator privileges in the Windows installer is an absolute show-stopper for me. I do not have administrator-level access to my company laptop (Windows XP), and BP does not run on my personal laptop (Ubuntu). I do not know how many users are in a similar situation, but I am completely unable to use BP in any fashion at this time. But even if I could run the installer, and I developed a BP-enabled service, I wouldn't want my users to need admin rights to use my service. Right or wrong, many large companies don't give out admin rights, and for what I want to do, those users are exactly the kind of users I am interested in serving.

So not only can't I use BP myself, I wouldn't want to develop anything which depends on it. For me the *only* reason to develop on BP is that Web-based deployment is the easiest possible thing for users, and requiring admin access utterly defeats the advantage of browser-based deployment. If I wanted a complex install involving the registry, etc. I would write a desktop app.

I think the YUI library is excellent, and really would like to put it together with BP to create a full-featured, browser-based app. Please consider developing a non-admin install process. Cheers!
