A feature to provide the ability to upload and run an arbitrary executable using finspy, and to extent finspys cloaking and personal firewall/av protection to the new executable. For example:
 
- hide the executable on disk
- hide the process from process listings
- start and stop the executable as desired e.g. start on finspy startup
- apply firewall evasion to the new process
 
In other words, treat the new process as an extension of the finspy process and provide the same cloaking/evasion features already present in finspy to the new process.
 
Depending upon how finspy is implemented, this may be an easy change, or it may be quite complex. It would be interesting to get your thoughts on the feasability.
