What about XFP? Any need for that as well?

Price would indeed depend quite a bit on the volume, since design and 
production cost will need to be recovered.

I'm not looking for commitments in any way; just an indication of how 
often people need a solution like this to get an idea of the type of 
volumes we're looking at, and a reasonable selling price. As written 
above: design and production cost (including test, validation, factory, 
etc.), and reseller profit margins will need to be recovered, so if I'm 
to convince our management that we should develop this product I'll need 
to build some kind of business case for it. Of course we'll also contact 
our regular customer base about these matters, but I would welcome 
feedback from this list as well.

Kind regards,
