This will not work as it is by definition inserted between 
\begin{frame}...\end{frame}
like thus:

\begin{frame}
.
{
\end{frame}

\begin{frame}
.
 }
\end{frame}

I think it it possible to write a function that prepends
{\myfunction..etc   and appends } to the frame environment.
For the time being a property like BEAMER_BG: myfile.jpg could be
harvested and transformed into:

{
\setbeamertemplate{background canvas}{
\includegraphics[width=\paperwidth]{./myfile.jpg}

\begin{frame}
.
\end{frame}
 }

The latex code could be a bit more elaborate and the image placement
attributes need some automagic, but as a proof of concept, this will do.

I do think I need a little help with this though, as I have no clue
about org's inner workings. 
But let's take it one step at a time, like how does one harvest the
BEAMER_BG: myfile.jpg property ?

I see the limitation of my suggestion one now. I guess the only way is
option two then.

This page from the manual might help you.

http://orgmode.org/manual/Using-the-property-API.html#Using-the-property-API

A combination of getting the properties with the property API and
adding your own function in the post export hook might be the easiest
solution here.

Good luck, and do post back to the list if you find a solution, I
would be interested.

 A quick look at org-beamer.el makes me think that there is no infrastructure
 in place that accounts for enclosing each frame in its own tex environment,
 although I think that would be trivial.

The other option might be to write your own function and add it to one
of the export hooks.
