Setting Up Remote Access On Own Domain W/o Cert?

Quick version: Can you set up remote web access to use your own domain without buying a security cert?


Longer:
I set up a new WHS2011 box. I'd like to have remote web access to it for a variety of reasons (file access, remote desktop for when my wife breaks something during the day, etc).

First I used the standard name.homeserver.com setup. Worked fine, but I've found that a lot of places I go have homeserver.com blocked (along with dropbox and other web storage sites - looks like some of the filters that companies use have "online storage" as a category to block, and lots of places do block it)

So then I tried using my own domain. I own a number of them, a couple w/ godaddy and most w/ 1and1.com, where I do my hosting. The setup to use godaddy seemed to go ok until I got to the screen where you need to pay for a security cert. For me, the web access is nice, but not something I wanna spend a bunch of cash on.

I can set up any subdomains, redirects, etc that I'd need, and UPnP seems to be working great on my router (dd-wrt'd Cisco E3000), or I could use a dynDNS setup, or whatever. Doesn't really matter as long as it doesn't use the homeserver.com domain.
