Edit Data - YES.
Edit Structure - NO.
For data entry/editing you would normally have a split database where you have a Backend (with tables only) sitting on a file server where everyone has read/write/delete rights and then you have a frontend which is linked to the backend and then a COPY of the frontend is distributed to each user to put on their computer.
Then you keep a master copy to do development work in and then redistribute when you release a version. You can use an AutoUpdater to keep the users having the latest copy, and there is a free Auto Updatae Enabling Tool on my website you can use, if you so desire. There are others out there as well, including Tony Toews (pronounced TayVZ) who has one.
