link ~/.eMule to some publicly readable (and probably writable) config file.

files in ~/.aMule, mostly yes, but config file (that is, ~/.eMule, no).

I never tried and, what's more, I wouldn't recomment it, because of the famous newline char incompatibilities between Unix and MS'S OSs, but you ca try linking fomr ~/.aMule/ to the eMule files. Remember the files MUST have write permissions.
> If not is it possible to make win aMule and aMule to use same files?
Config file has a different format thatn eMule's. Also, aMule has different preferences (some more, some less, than eMule)
If possible, keep aMule as aMule and eMule as eMule ;-)
I hope that helped. Greetigns!
