Passing instance of PluginAPI around

[h1280]

Is it ok for other non-plugin classes to obtain a reference or even store it in the class's field?

Sure is. I've done it myself. You want to be careful not to cause a memory leak, but other than that, go for it. In 2009 I was on a team where we passed the same api object to dozens of non-plugin classes.
