As already stated in this thread a few times, the BSD checksum is far from perfect - its major advantage is that it's extremely simple, hence fast to compute even on a 8088, yet at the time it is reasonable to assume in normal conditions (ie. no malicious intent) that a file that shows the same BSD checksum before and after a transfer is indeed the same file. Still, since you mention "stronger" algorithms, it might be interesting (if not entertaining) to see how the BSD checksum compares in terms of collisions to other algorithms like CRC16, CRC32, Fletcher, etc. I did try to google that out, but unfortunately the BSD checksum is rarely mentioned in this kind of research. Would you mind sharing some links that explain how much stronger the other algorithms are, and what are the actual chances of hitting a collision by accident with BSUM?
