This isn't a limitatin of TOPS.  Rather it's part of the AFP spec. (that
stands for Apple Filing Protocall).  Unfortunately I don't have my
Appletalk Bible handy, so I can't quote chapter and verse; but basically
there are differences in the way that directories are implemented under
DOS vs. HFS; enough so that a feature needed for HFS isn't there in the
DOS envorinment resulting in the inability to make a one-to-one directory
mapping from DOS to HFS (ie you have to make each directory on a DOS volume
act as an MFS volume of it's very own, and mount them seperately).

Sorry for the lack of details; this is from a skimming of AFP two months
ago.
