APIGee allows you to monitor and test api usage. I've signed up and the api2 api is available with api2.esme.apigee.co.
I'll do the twitter api next. The advantage with using apigee for this api is that we can see exactly how various twitter clients are using ESME and what sort of problems they are having. I'll keep you abreast on what I learn. This api is available with this URL: twitter.esme.apigee.com. Please use this when connecting with any client (Tweetdeck, etc.) Have fun. D.
