I believe the only logical restriction is with IDs, so given that the 
engine doles out a new ID for every object, even cards, regardless of 
type, the total number of objects in a stack is 4,294,967,295.

However, for most practical uses you'll find that performance begins to 
bog down at about 5,000 cards, and finds, sorts, and saves are 
prohibitively slow at 50,000 cards for most uses.

And then there's memory:  unlike systems that page parts of the file 
from disk (DBs, FMP, HC, etc.), Rev loads an entire stack file into RAM. 
  This makes for good performance and more flexibility with when things 
are saved, making even traditional document behaviors a snap.  But it 
does mean that it can use more memory if you're loading large stack files.

But there are so many ways to work with data in Rev, to help find the 
one most suited for your project can you tell us a bit about how many 
cards you anticipate needing and what you want to store on those cards?
