Did you consider using GemStone as a server platform? The VisualWorks
interface is very transparent, so there should be no impedance problems. 

GemStone is maybe the better choice since it gives you multi-user
capabilities, transactions etc. Essentially, it's a multi-user Smalltalk
implementation with database functionality. Also, GemStone is already
being used in large 24x7 production environments. I mean, that's what
you're talking about, isn't it?

Just a developer's thoughts...
