Yes I mostly agree with your analysis, database is the only significant
potential market for IB.

However the problem with 1GBE or 10GBE is that the latency remains poor
for HPC applications, while IB goes in the right direction.
The real comparison to be made is not between GE and IB, but between
IB and Myricom products, which belong to an especially protected niche.
As a result for years the Myrinet products did hardly drop in price
for a sub-Moore's-law increase in performance, because of a lack of
competition (the price we paid for our Myricom cards and switch
18 months ago is today *exactly* the same).
Now IB at least introduces a healthy stimulation for this low latency
HPC sector.
