title: Can you safely rely upon Yahoo Pipes to offload ETL for your application?
body: <p><a href="http://pipes.yahoo.com/" rel="nofollow noreferrer">Yahoo Pipes</a> are a very intriguing choice for sort of a poor-man's server-free ETL solution, but would it be a good idea to build an application around one or many Pipes?  I've really only used them for toy things here and there, with the only thing I've used longer than a week or two being one amalgamated and filtered RSS feed that I've plugged into Google Reader (which has worked great, but if it goes out for a while I wouldn't notice).</p>
  
  <p>So, my question is, would building an application around Yahoo Pipes be reliable (available most of the time)?  Ideally it'd be something I could rely on being up 99+% of the time.</p>
  
  <p>It looks like the <a href="http://info.yahoo.com/legal/us/yahoo/pipes/pipes-4396.html" rel="nofollow noreferrer">Pipes Terms of Use</a> permit building apps around it, but I am unfamiliar with anyone building anything significant using them.</p>
