This is possible 13.10, at least it tested well in my VM.
The older scripts do not work as you(Seth) have discovered. However the newer scripts that worked for 12.10 and 13.04 work for 13.10.
The site webupd8.org has the instructions. As is stated, the instructions are for 12.10 and 13.04 but I tested the one in Virtualbox and it worked flawlessly(well as well as they did in 12.04 up, there are a few limitations as noted in the article but all in all they work well)
Unfortunately, the ppa for Saucy has not bee updated to include these scripts (at least not as far as I was able to determine) so the only solution is to download them directly.
There are 2 different scripts and they cannot be installed together.
The one script only dodges maximized windows. It's biggest limitation is that it will allow the launcher to overlap any windows that were opened while it was hidden.
The other script brings back the old style of dodging windows(almost) in that it will hide the launcher when any window is in it's(the launchers) space. The biggest limitation that I noticed is that if any window is open that is in the launcher's space, the launcher will stay hidden even if that window is minimized.
Here is the link to download the Dodge maximized windows script
Here is the link to download the "original" dodge windows script
The download links that I included above come directly from the article on webupd8.org.
I would suggest that you read the article on webupd8.org that I linked to at it gives a good rundown of the scripts, (I don't want to get into plagiarism territory by including too much of the article.
In the interest of full disclosure, I did not play too long with the 13.10 VM but in the time I used it I didn’t notice any unexpected issues with the dodge windows scripts. I also did not play long at all(maybe an hour) with the "original" dodge windows script as the hidden launcher limitation I mentioned above was not to my liking. The dodge maximized windows script has seen maybe 10+ hours of use with success.
As an editorial note(read my opinion, which in worth exactly what you paid for it); These "dodge windows" question and workarounds are all over AU and the internet, I don't understand why Canonical is so married to the idea that it was a bad feature. Yes I have seen the articles about why they removed it and it seems like "thin soup" to me, obviously many user want it, and the scripts work well enough.
To give credit where it is due(I think*), I believe that @JorgeCastro wrote the first work-around script back in 12.04(the dodge maximized windows one). Thanks a bunch Jorge, this missing feature was a deal breaker for me and I was considering switching away from Unity(was considering Cinnamon but it was buggy, so you really saved me at least.)
I have taken a bit of a liberty in including this editorial, and my intention was not to start a discussion on the subject, just to state what seems to be a common opinion in the Ubuntu community. Please do not respond to this as a discussion, or I, or the mods will be forced to edit or delete this answer.
