You can take money for additions to the code and/or support of the code,
however additions and/or changes to the code must be made available to
those who request it *under the same license* for a nominal fee (e.g.
cost of media which is not much in internet times).
A possibility for making money is by implementing special things on a
contract basis. However once the code is available, the gromacs team can
decide to incorporate it in the standard distribution and then it will
be harder to convince potential users to pay you.
