We have a stack that will total approximately 30 megabytes, for about 12,000
cards.  Do we really want to run it using HyperCard v.1.2.5?  We plan to
distribute it commercially, and would not wish to make all of our users switch
to system 6.0.4 willy-nilly...

- Does HyperCard 1.2.5 simply run large stacks more efficiently than 1.2.2, or
  are there substantial changes in functionality?

- Do the two versions use the same file format, so that we could develop using
  1.2.5 and distribute for use with 1.2.2?

In addition, any comments from people with experience developing multi-megabyte
stacks would be most welcome!
