Don't forget that the scalability issue in distributed computing has almost *always* been about making algorithms or similar computationally intensive codes execute faster. You'd write your codes that could either parallelise easily or pass onto a decent resource manager to farm out to a super computer or commodity cluster.
Grid computing typically involves the sharing of organisational resources with other like-minded organisations - consider the US national labs that use Globus, or the ever-increasing EGEE grid hosted by CERN and other academic institutions across the EU.
One of the problems businesses have with Grid computing are the security aspects, protection of IPR. At the same time, they want to reap the benefits of computation resources they would otherwise not have access to. Academia has not had so much of a problem since computation resources are purchased on public funds and would not eat into profits - not true for business who have to look at the bottom line.
Reliability is an interesting issue, but like you said needs to be supported by the middleware *and* resource manager in question.
