70 bytes ?? My name is 18 characters long and there are plenty of people 
with longer names. I also saw practice on Windows systems to append the 
name of organization or department.

Also, this restricts the length of package name which is arguably more 
important that internal package path names that the user never sees.

That said, that Windows limitation is only for some programs, and the 
pertitent question is whether R and any software used by R has this 
limitation. I suspect the answer is no, but as all my systems are Linux
I can not check.
