I wanted to get the difference between a 1 user cal and a 1 device cal for SQL Server 2005. in particular if we have 2 users connecting to a SQL Server each from there own Pc's, what licence do we buy. There is no web involved here. Also, If we get a third person in a years time how do we buy an additional licence? The reason I ask ths is because, I can buy for under AUD$300 a 1 user Cal or a 1 Device Cal, but then a 5 user licence jumps to over AUD$1,500 ???
