Lynn,
How are you going to "bundle" any of those programs?
Are they going to be like the"Quad-Lock Unit Converter? that can be call when need it?
Or every time you open EVO a spell checkers is going to be load (into your memory) as well.
If this is the case please make sure that:
There is an option to include it or not (some customers might not want it)
Make sure that you include any "requirement" like net framework, visual studio runtime, etc, etc.
By the way,
There are lots of dictionaries that can be easily add as an API library (free of charge).

PD: YaBB has one, that is why there is not spelling mistakes (LOL)
