You could wrap the OS ping variants (Linux and Mac OS X are probably 
identical, since both use the GNU utils, so you only have to check for 
Windows) in your own code, and use that.

They all should provide a means to modify packet size (Windows' ping.exe 
does), so you can achieve your desired result.
