Some other online tools for filtering RSS

UK_M5_Traffic currently uses Yahoo Pipes to filter and manipulate the RSS feed it's based on but I came across a post on Read Write Web that lists some other online tools that might be worth exploring. ZapTXT looks to be the most interesting but won't send text messages outside the US and Canada at the moment.

In the short term I'll probably carry on using Pipes as I'm now using it's regex features to cut down the message to make it a bit more punchy and readable.
