Help with backgammon simulation

Our backgammon group is looking for online play options. In addition to standard tournament play, we play a group backgammon game called chouette. There is currently no online platform that supports this common style of play as it is usually done in person.

Here are some features that we need.

- multiple people playing on either side of the playing board, instead of the usual one on each side - multiple doubling cubes, each player has their own - switching the active player mid-game on either side of the board

Scorekeeping is a nice to have, but we can track on the side.

Questions:

Does each player need to own their own copy of the tabletop stimulator program? I assume yes.

Can we use the standard backgammon program that is included by default and extend its functionality and flexibility?

If this is possible, how do we go about finding an experienced person to help us implement?
