What you are proposing is something similar to Google Native Client (http://code.google.com/p/nativeclient/ 
), except that they also added code verification because it's intended  
for running native applications downloaded from websites.

That is not directly related to packages, but rather to a completely  
new run time environment with its own ABI, object format etc. The  
result of having such an environment is indeed that you can have  
compiled binary code that is portable across different operating  
systems, but that's outside the scope of adding packages support to FPC.

You first have to define such a platform (or you can take the Google  
Native Code platform), then add RTL and compiler support to FPC for  
that platform, and subsequently any program or package compiled for  
that platform by FPC will run on it. Reinventing such a platform and  
embedding it in FPC and its run time library falls outside the scope  
of the FPC project.
