Authenticated Feeds with Google Reader

Recently i wanted to include my status updates from XING into Google Reader. Turns out that Google Reader has no support for (HTTP) authenticated feeds. There is however a service called FreeMyFeed that takes care of this by proxying these feeds. Although they claim to not store any of your credentials i would not use it for sensitive data. This is not only because of the credentials but also because the obfuscated URL you will end up proxying through is of course unauthenticated and a leak would mean anybody can see the feed content.
