Do you have a guaranteed way to keep that store up to date? Is that a
requirement or can there be latency and the app still be effective?

If so, I can certainly understand although I don't think you're going the
right direction. I'm not sure it's a good idea to base a solution on
something that Microsoft doesn't even support outside of development
environments. (Last I checked ADAM wasn't supported on XP outside of
development applications. I haven't checked lately however so it may pay to
double check.)

Do these copies on the laptops need to be writeable or read-only? I'll
assume read-only for now but please correct if needed. What you would be
looking for is some sort of network aware client-agent that will wake up and
synch the db either on schedule or automated depending on the app. In that
case, I'm not sure I'd go with a single configuration set but rather I'd
probably make each independent since they're just copies anyway.

I suppose the spec would be something like:

On wake-up check which network you're on
+On home network, sync at will according to configuration settings.
++Optionally, set a schedule and try regardless of network
+When not on home network, allow user to choose to sync, not sync, or set
sync schedule

Basically, the same as an Anti-Virus product.

I haven't seen any products out there aimed at such an application; doesn't
mean one doesn't exist but because of the support path it is not likely.
The folks at cps-systems might be interested in helping with such a solution
for what it's worth. http://www.cps-systems.com/products/default.asp or
even the people at Cassioware http://www.cassioware.com/cwpd.aspx although
that's not a traditional space they seem to want to play in. Assuming you
can get them to want to write an app for an unsupported configuration else
get Microsoft to change their stance?

Would be nice to have some dev team resources chime in here as well. I
realize this is normally outside the scope of many of the intended uses of
ADAM, but it's probably not an uncommon desire as we still have to deal with
computers that are more and more mobile. If ADAM is to be aimed at
standardizing the directory that an app uses, then a way to achieve should
be available conceivably one that doesn't require a "roll your own" effort.
Maybe an ISV could be incented to create such an animal: it would be of
value.
