Build TTS plugin

I'm interested in having a wordpress plugin where text on both the front end and on the back end (the editor form where articles are written) can be selected (highlighted) and a speaker icon would appear at the end of the highlight text. When the icon is clicked on, the selected text would be read out loud using the [login to view URL] api (I'm not interested in the talking head, just want the words read). Other highlight functions, such as copy/cut/paste, should not be affected. So, for example: 1) a reader could be reading an article on our site and select the text, an icon would appear, and they could click on it to hear it read and... 2) a contributor could write a story, and while remaining on the edit/new-post page, select the text in the form and have the same thing happen, an icon would appear, they would click on it, and it would be read to them. Sitepal has an example javascript calling the tts dynamically here: [login to view URL] The plugin would need to overcome the 600 character limit on a dynamic call if more than 600 characters were selected. Examples of that are here (I'm not sure what methods you would need to use): [login to view URL] [login to view URL] You will need to have a current version of wordpress you can test this on. You will also need to sign up for a sitepal account so you can access the api. You can sign up for a 14 day free trial to build this. No fancy settings page or anything like that is needed. I can put my subscription info into the script, just give me a place for that (you'll need to have it there to test it anyone using your free subscription). I'm not paying you to build this for me and then go sell it online or put it onto wp as a plugin. If you want to do that on your own, you can and I'll use it. If I'm paying you to build this though, it's mine and you don't reuse the idea and code. Agreed?
