[Live-demo] Disk Space and MapGuide

Thanks for the analysis. I realise that there is often a lot of work 
reducing disk size, and I'm hoping that we should have one or two 
releases before we will be forced to face the really hard decisions 
involved with reducing disk space of installed applications. (The easier 
decision will be to move Windows and Mac installers off the mini version 
of the disk).

What I suggest is that MapGuide (along with other applications) start 
planning for this, and start making decisions within the project which 
will result in a reduced disk foot print.
