Thanks to Hank for reporting that a MSSQL ODBC driver is now available for Linux x64 from:

http://msdn.microsoft.com/en-us/library/hh568451.aspx

This allows Lianja Apps running on Linux to access MSSQL running on Windows.

The Lianja Small Business Edition and the Lianja Cloud Server Appliance will have this pre-installed and will be available as both a Hyper-V VM and a VMware VM.
