Ladies and Gentlemen,
There are a couple of minor JIRA issues related to the JetDriver and we are leaving it open (for now) for those who are interested in contributing but don't know where to start. The issues are:
In NH-1181, all that should be needed is to register the "ucase" and "lcase" SQL function.
In NH-1132, all that should be needed is to change a parameter in the call to RegisterColumnType() from "UNIQUEIDENTIFIER" to "GUID".
Both are trivial fixes. It will probably take you more time to set up the environment to develop and debug NHibernate than it will take you implementing the fix. Have a look at this article for instructions to set up your environment:

Feel free to email me directly if you are stuck.
Thanks in advance.
