There are, unfortunately, fatal issues with this. The vfat filesystem
doesn't store ownership or permission information. This means that, as far
as Linux is concerned, all the files on the vfat drive have the same owner
and permissions. For storing data (e.g. sounds, mp3's, graphics) that you
don't plan to edit regularly, this might work, but for executable programs
it's a wash. I can think of three alternatives.
First, you can repartition and give Linux more of that extra space. FIPS
and Partition Magic are two programs that can usually shrink a partition
without losing data.
Second, you can use the "umsdos" filesystem, which uses hidden files to
store ownership and permission information. This is supposed to be pretty
slow but workable.
Third, you can try using a "loopback" filesystem. You create a file on
the vfat drive, and then mount the file as a filesystem. You need to
compile in kernel support for this. This works, and gives you a "real"
ext2 filesystem. However, if you're running Windows and something
overwrites that file, you're hosed.
Hope this helps...
