The use of the feature may be under debate, plus, this is crude patch, because dtella does not update minshare from 1 for the current setup.

Aren't global level values in a separate config.py file?

[ParthKolekar]

There is no config.py that I see...
there is

bridge_config.py
push_dconfig.py
pull_dconfig.py

There is indeed one value I remember trying to set in the config, but the init set's the value to be 1 (1 byte) and the config is never read. The 1 byte stays until the end of time, and is not even changed ever.

I have allowed AGREED_UPON_MINSHARE var which is actually read by the and used.
