I understand that feasibility could be a concern in the sense that "we cut down memory usage without *any* loss in performance* because that would depend on how well we can tune the cache. I was thinking that the file backing the tvbuff would be a separate file and not the capture file. In that case, encryption and compression of capture file wouldn't matter. Am I missing something here?

On second thoughts, we don't need a separate file for backing up the tvb. But, if the file is compressed etc then the cache misses are going to be more costly. So, I get what you mean't there.
