I hope this is a Windows version of the package called fame already on 
CRAN. Otherwise, you need to think of a different name, and it would be 
nice to have versions that work on Sun and Linux, not just Windows.

Just remote linux machines, or does it handle remote Sun machines too? 
Does it handle the endian problem?

I'm confused.  If you want the user to be able to make a run time 
decision then you can't make this choice at install time can you?  
Should you not be installing both  fame-local.dll and fame-remote.dll 
and then deciding at run time which one to call?  (If this package is 
doing what I think it is doing,  then users would want to make a run 
time choice. Actually, often I would want to use both at run time.)
