Strictly speaking you have to offer the source on a physical medium.  
A download possibility (web/ftp/email) is not enough.

Since I guess nobody distributing XviD will really send out disks or CDs 
with the sources by snail mail if asked for by thousands of users. So it's 
a very good advice him to simply put it on the binary CD-ROM, and not 
explain the unreasonable alternatives.
