Fuzzy date and normalize
You can now get fuzzy date times such as 2 hours or 10 minutes (from Trac) in JSONP by hitting clearwind-labs. For example: http://clearwind-labs.appspot.com/fuzzydate?start=2008-10-06%2012:32:52.
Normalize is the Plone code for normalizing id's available as JSONP too: http://clearwind-labs.appspot.com/normalize?text=sterreich%20has%20GREAT%20beer
These are over at http://clearwind-labs.appspot.com/.
I could keep going on this theme for ages, must stop and get some useful stuff done instead.
