Although I use a script for installing/updating corona on all ws/nodes (which works fine for me, at least if there are no additional installer packages to deploy), it would be indeed great and a more professional approach to have a msi to throw onto the domain controller and have it installed automatically on all boxes by domain policy, yes! Presupposed DrServer comes as windows service in future.
Not a high priority request for me (because I always liked the option of a manual installation very very much and corona seems to take care not to rely on some obscure registry settings like almost all other software) but something to definitely think about.
Good Luck
