Using MSMQ

I am designing and developing a system for supermarket, and I want to build loose coupling applications between the Point Of Sale and the Server / Back-Office.
My system should allow the Point Of Sale to work independently and exchange (synchronize) their data when the server is not available in order to keep the supermarket operational in efficient way.
I want to know, is it possible to utilize MSMQ to achieve that (specially between PC-PC not PC-Server), or it is more recommended to build our messaging / synchronizing techniques.

Thanks
