The bad news is if you are in cheap hosting or really most shared hosting environments, you are probably hosted in Medium Trust and if that is the case it may only work if the host has the same version of MySql connector that we depend on installed in the GAC or has customized their trust policy to allow data access without the driver being installed in the GAC.
It may work or it may not depending on your host. If not the symptom will be a security exception.
Hope it helps,
