[Ruby] MS SQL Server advice?

[ben wiseley]

I'm working with a startup that would like to integrate with OpenTravel CRM
( http://www.opentravelcrm.com/ ) which is .Net on MS SQL Server.  While
writing my own CRM isn't that scary - integrating with legacy travel systems
is.

Anyone have production level experience with Rails on SQL Server?  Is it a
total nightmare or not-so-bad?  I've heard it works, but does it scale up?
We'd run their CRM and SQL Server on a windows box and Rails on a Linux box
that connected to the SQL Server box (or possible do virtualization all on
Linux).
