  You may want to look at the size limits on resource forks, though. I 
thought I'd blogged about that ages ago, but can't find the posting 
right now. The resource fork format is documented, though, so it 
shouldn't be too hard to figure out. There's for example a 2727 
resources limit on each file, and some offsets are 16-bit quantities. 
So, it's not really a good idea to have resources of several megabytes 
in size.
