I don't particularly see the value, it would just be extra stuff which 
serves little value - we know it's a pointer if it's being used as a 
pointer, a specific class adds little, but would of course be easy to do, 
and might be of more value for non-RDF-y folk :-)

So it's 2 different pointers to the same piece of content? as opposed to 
multiple pointers pointing to different content?

I think that's fine :)  we should discuss if that's not the case.

For me it's extra cruft - but why not.

a Snippet can either have a byteContent or content or both predicates, I 
don't see a problem, could it just be a language problem in using

"Some content that is a snippet of a document, it has been base64 encoded." 
for the rdsfs:content ?

Again I can't see it, could it be my English language description that is 
confusing?

Cheers,

Jim.
