Upgrading Substacks Only

[Jim Biancolo]

Hi folks,

I was trying to figure out the best way to create an upgradable standalone 
Rev app.  In toying with ways of separating data from presentation I 
noticed that when I build a distribution that has separate substacks, the 
main executable is around 1.5MB (on Windows) while the substacks are much 
smaller.  This is true even when my mainstack is just a dummy stack that 
invokes one of the substacks on startup.  This got me to wondering if I 
could distribute the standalone EXE (and mainstack) as the engine, and then 
just the substacks during upgrades?  This would greatly reduce the 
bandwidth needed in distributing upgrades, it seems.

I did a successful test of this approach, but I'm wondering if there are 
any downsides I'm not seeing?

Thanks!

Jim
