You can be quite safe that all object structures you can also encode
as property lists (i.e. NSArray, NSDictionary, NSNumber, NSString) and
classes where you write your own keyed encodeWithCoder/initWithCoder
are portable.
I mostly only use basic data type (array, string, etc.).
So it seems to be fine as you suggested.
I will test it in my case.
Thanx.

I.e. the most common case is that your application has some model data
structures to be encoded during a Save operation in a (binary) file.
This should IMHO work without problems.
