>Has this person seen some limit that is hurting the business?

Not that I am aware of? This seems to be based on personal attack against the product.

>Has this person seen projections for future business that make him worry and, if so, how has he concluded that the current infrastructure can't handle it??

I would say nothing like that is in effect.

>As usual, this sounds far more like MS .NET "case study" reading - with all of the FUD that is mandatorily included in such diatribes - than any kind of actual FACT.

The problem is that person sits on top and that is locking our future development on several projects because of that POV.
