revOpenDatabase over SSH tunnel?

I do not think this is a mySQL issue. Livecode currently can only send one statement per query to *any* sql server, at least that is what I have come to understand. But I do not think issuing many queries from livecode is the bottleneck, but rather the ability of the SQL server to respond. When I use memory databases, the response time is nearly nil. A single mySQL query over a LAN is not even noticeable. I make maybe 15 or so queries every time I select a new customer in my Forms Generator app, and it isn't the queries that slow things down, it's the populating of the datagrids and fields that take time. 

Now on Windows, I think I do experience some delays with queries, but I think that is just Windows networking security overhead.
