You don't really have much choice - I'm certain that the mdb-tools
won't read from a remote ftp server and I suspect RODBC won't either.

sudo apt-get install mdbtools
should get you what you need to Hmisc to work. It works for me - but
you do have to download the data file. It won't work via an FTP
One possibility is to set up an FTP-based file system - basically an
operating system 'hook' that presents the FTP site as if it was a
local set of files. Have a look under the 'connect to server' options
on the ubuntu menus.
The real solution would be for the data to be supplied from a
database server at their end, and you could get the latest data using
RMySQL or whatever.
Note that I can't find any geographic coordinate info in the mdb you
referenced - if this is, as I suspect, an ESRI Geodatabase, then you
won't be able to get polygons or point locations.
