Many thanks. Will read.

I am sure they where. It's both interesting to see how they went on
doing it, as well as seeing if one can hack it into pieces. Part of the
process I guess.

Getting a connection setup should not be too hard, but it depends on
number of details, but it is being done on commercial basis. A two-way
transfer system (a few different options may be available) can then use
