[Plugin: Savrix Android Market] Caching?

Hi,

Looks like a useful plugin. Would it be possible to introduce some form of caching? (like this plugin has: http://ww.wp.xz.cn/extend/plugins/android-market-badge/). A previous plugin nearly brought down our server, and the linked plugin is way too difficult to setup.
