If you mirror the FTP site to a local folder, then it should theoretically use the incremental updates, which are about 100-150k in size. These should not be a problem for dial-up users. Make sure the the UPDATE.INI and DELTA.INI are also in the same folder. The .EXE files, I agree are too big for dial-up users.
