Is there any tool or ssh extension that would bring these apps into the remote session?

Is something like that possible? Seems like you could conceivablely dump these small file size tools into a temp folder and and use them and that could be automated.

Is there a security issue with that? Do any of these tools need more permission than the remote session would have?

Maybe the main issue is portability of these apps?

This is certainly a common sentiment (I've felt it myself) so is it at all possible?
