I would also like to do this. The primary reason is that I am not using the office live website as my primary domain and am only using Office Live as a CRM engine. I have multiple other domains that encompass my company so to get around this, I had to create a home page with links for anyone that clicks on visit our web site in email campaigns. Kind of a pain for the user/customer to have to go through this extra step.
I am hoping that MS also adds some new features to their editor soon because it is extremely limited.
