The flange distance of R mount is 46.9mm ... for Minolta A mount it's 44.5mm, for EOS mount it's 44mm, so an adapter is perfectly doable for both Canon and Sony cameras.
The guy who tried to convert the lenses actually took off the R mount and machined a new mount to fit the A700.

Yes, that's the "Auflagemaß". And thanks for your research of the numbers. They explain why your friends solution worked. Should there maybe be some pictures made with R lenses on A700 on the web?
Your friend converted the lens itself. I think I remember now what I read somewhere. If I remember correctly the diameter of the Canon mount is quite large compared to the A mount. Therefore adapter solutions work for R-to-Canon but not for R-to-A. The R lenses have some parts that don't fit into the A mount because their position is too much outside for the smaller diameter of the A mount.
If that's true R lenses would have to be changed permanently to be used on A mount cameras whereas the Canon solution works with an adapter and one can easily switch between Canon and Leica cameras.
