Yahoo Pipes can also be used for feed authentication (like Twitter Friend feeds). You could embed the username and password directly into the URL (in which case, everybody can see them), or you can hide them within a private string object, like this.
With a feed like that (with your own username and password), you can view your friends feed from Google Reader.

Unfortunately, Google Reader checks my Twitter Pipes feed every 3 hours. Is there a way to get Google Reader to check it every 15 minutes?
Keep in mind that you also have to deal with the delay on Yahoo's end, too. It's a long pipeline from the original tweet to your eyes. For example:
Friend tweets at 01:00
Yahoo runs the pipe to check the private friends feed at the next regular interval, say 03:00, and updates its public feed.
Google Reader checks that public feed at its next regular interval, say 05:00.
You check Google Reader when you get around to it, say at 07:00.
I don't know what the actual numbers would be on average. If you got really lucky, it'd be something more like this:
Friend tweets at 01:00
Yahoo runs the pipe to check the private friends feed at the next regular interval, say 01:01, and updates its public feed.
Google Reader checks that public feed at its next regular interval, say 01:02.
You check Google Reader when you get around to it, say at 01:03.
You can take full control of making the feed public if you do it yourself with something like curl. Here's an example of the CURL way.

Unfortunately, Google Reader is pulling both feeds at 3 hour intervals, which is just too long! I found this article describing how I can ping Google Blogsearch to notify that my feed is ready, but I'm unsure if it's having any effect to increase the frequency of GR updating my server's and Pipes' tweet feed.
Here (at the bottom of the post):

Just wondering if you or anyone else knows if pinging is supposed to increase the frequency of GR pulling specific feeds.
Or do you just have to trust that Yahoo's connection to Twitter (or any other service requiring authentication) is reasonably secure?
If you figure it out, will you post what you discover in a reply?
FWIW, if I need SSL to protect data, I wouldn't give the data to Yahoo pipes to store on their disk in the first place.
