Thanks for your response and sorry for taking some time to respond. I am traditionally not a programmer and a bit lay here, so please permit my layman's self expression. :)
Yeah I am aware from the little I have read that the G.Drive API may not work for me. But with what polymer offers, I think it allows whatever element or content it generates in the DOM to become part of the DOM and as such functions like COMMAND+F should work fine, a function which fails for iframes. If this is true, then that is the solution we wish to implement, and as such I can invest the time to learn polymer (which by the way sounds really interesting...really).
An added functionality I wish will be possible if content generated can be optimized for Search Engines.
I hope I was able to communicate :)
Thanks for your time.
