As said by Satbir15, most of the problems are with the sheer legality of a portable DRM remover (For example, the DMCA does have clauses designed to criminally prosecute those who create technologies to bypass DRM).
As DRM has been created and is used exclusively to prevent unauthorised copying of proprietary works, a DRM remover could be an extremely useful tool for aiding the piracy of that said works.
With that aside you should mention Da_Boom what DRM removal application in question you wish to be portablised using the template on this thread: https://portableapps.com/node/4507
illegal is some countries, would get them in trouble like a portable proxy
