We are designing a sales-forced automation tool, where the sales-
force need access to current systems/data even when they aren't 
connected to the network, i.e. clients office. We're looking at 
using web services & MSMQ to synchronize data between the clients 
and servers.

I know the plusses of using MSMQ (guaranteed delivery, asynchronous 
communiction, etc), but can anyone outline some potential problems 
that we might face using MSMQ.

Any reccommendations?
