Orbeon XML to URL converter
Ok, you may have to repeat this to yourself a few times to sorta "get" it.
This is a web service which allows you to send it an xml snippet. This snippet is converted to a "url" which it sends back to you. You can then later visit this URL - and the server will return your original XML data. So basically it serializes and compresses your XML into a string and makes it a url. The neat thing is then you can pass that to a service like tinyurl.com
