"play nice with others" is a misnomer.
As I replied to Tom, apps are generally unaware of each other's existence
except where they have code specifically written to address this question.
The only reason SBS-default apps appear cooperative is that the SBS team has
tweaked them that way.
Rather than trying to adjust MSDE for ISA load, it should be throttled for the
max memory you want to allocate to the system.
Since this is a variable, we'll need to figure some sort of algorithm for it
based on the SBS installation.

You may be correct but because we have several instances of MSDE and an
Exchange store running. That amounts to at least 4 services all using all
available ram and saying that they'll play nice with others. In practice it
doesn't work so well. My solution has been to limit the MSDE instances and let
Exchange run free.
Currently I'm just playing by ear with the MSDE limits. I'd really like to have
something empirical to set the MSDE limit to.

This is a good question, because my impression is that MSDE uses only the
memory that is available and iff another service requires the memory, then it
releases it. I know that this isn't an issue in a proper deployment of the ISA
firewall. But the SBS deployment would be an interesting academic exercise.
