Sure. Do the same thing you'd do if you had two non-template bases.

That's what I thought but either I don't understand it (obviously...)
or the compiler doesn't support it. Here's a more complete example,
compiled with VS 2008:
First write analogous code that doesn't use templats. That way you can
get something that works and gives you good guidance when (or if) you
switch to templates.
class BS :
public PortProvider<MyData, 1>,
public PortProvider<MyData, 2>
{
public:
BS() : PortProvider<MyData, 1>(), PortProvider<MyData, 2>()
{}
virtual ~BS()
{}
virtual MyData PortProvider<MyData, 1>::getPortValue() const
{}
You're not allowed to define a base class member function in a derived
class.
Again, lose the templates and the virtual base. Then sort out how to
write the code and get it to work. Then add the additional stuff, a bit
at a time, checking that it still works after each addition.
