When I started doing presentations with beamer, I kept getting caught out by the fact that I'd forget exactly when the end of a frame was going to happen so I'd jump to the next frame before I intended as I wasn't sure that everything on the current frame had been displayed. (Now, of course, I print out the handout version and have it in front of me.) So I came up with a hack that modified the title when it was on the last frame to give me a visual clue that it was the last frame. This might be adaptable to what you want (though there may well be a better solution) as it uses a counter to keep track of the last frame number. It's not completely robust as it can get confused if a frame changes size radically between compilations (in which case, delete the aux file).
This was my "experiment" file to test the system. It also allows for one to define an "offset".
\documentclass[12pt,color=dvipsnames]{beamer}
\newcounter{last}
\newcounter{lastoffset}[framenumber]
\setcounter{last}{1}
\setcounter{lastoffset}{0}
\newcommand{\last}{%
\setcounter{last}{1}%
\addtocounter{last}{\insertframeendpage}%
\addtocounter{last}{-\insertframestartpage}%
\addtocounter{last}{\value{lastoffset}}%
}
\newcommand{\lastlabel}[1]{%
\last%
\label<\value{last}>{#1}%
}
\definecolor{last}{named}{purple}
\newcommand{\lastframetitle}[1]{%
\last%
\frametitle{\color<\value{last}| trans:0>{last}#1}
}
% Either: \reset redefines \last
% Or: just redefine the \lastframetitle and \lastlabel to the originals.
\newcommand{\reset}{%
\renewcommand{\last}{%
\setcounter{last}{1}%
}}
\begin{document}
\begin{frame}
\setcounter{lastoffset}{-1}
\lastframetitle{Example Frame}
\lastlabel{ex}
\arabic{lastoffset}
\hyperlink{ex}{\beamergotobutton{Last Slide}}
This is an example frame.
\pause
Wait here
\pause
Paws for Thought
\onslide
Visible all along?
\end{frame}
\begin{frame}
\lastframetitle{Second Frame}
\arabic{lastoffset}
This is the second frame.
\pause
Another slide appears
\pause
Yet more appear
\pause
Wait until the end
\onslide
Should be here any time soon
\pause
What's going on?
\onslide
When do all these appear?
\pause
Phew, that's all folks.
\end{frame}

Here's something that works with the example you posted, but might not work with more sophisticated overlay specifications. There are two parts to the method. The first is a little addition to the overlay code which tries to establish whether the current frame was explicitly mentioned, for example the 3
in \uncover<3->
, or not, for example frame 4
in \uncover<4->
. If explicitly mentioned, it sets a flag. The second part to the method is a little addition to pgfpages
, imaginatively called pgfmorepages
(CTAN and github), which - amongst other things - introduces the possibility of skipping a page when shipping out pages. So this looks for the flag set by the first part of the code and if it doesn't find it, it ignores the particular page.
There is a snag. You can't use the transparent
option. That is because this does some look-ahead stuff and asks "Is this going to appear in a frame or two's time?" So it runs the overlay specifications with other frame numbers than the current one and that messes up the testing.
The other annoying bit is that each frame has to start with the command \mentionedsetup
. This could be automated by adding it to one of the templates.
Here's the code with some sample frames.

Oh, and we have to redefine the \note
command. Even when the notes aren't shown, the command is processed. So we have to redefine it to be a NO-OP to ensure that the resulting overlays aren't read.
Here's the first few frames of the above, showing that frames 2,4,6 get skipped.

You may want to have a look at the
handoutWithNotes
package.Which gives you (with the
Berlin
) theme:You can find some examples here: http://www.guidodiepen.nl/2009/07/creating-latex-beamer-handouts-with-notes/
I didn't find this package on CTAN. So it won't be in your LaTeX distribution and you need to install it manually.
