The FujiNet NOS has XIO 39 and 40, which can load binary files. It's the same loader that's built into the command processor, and can load files from any network endpoint.
How about a front-end is made for a8.fandal.cz or homesoft, that can be searched?
The option to search files among given server would be cool functionality in Fujinet menu. Now one has to navigate to the desirable folder manually which takes some time.
