Based on preliminary info and demos from Lawson, LBI uses MSOLAP/Hyperion Essbase for multidimensional/OLAP analysis.
1. Would the multidimensional cubes (MSOLAP) be loaded directly from the Lawson transactional tables or from the tables in the star schema?
2. Can MSOLAP export files in a relational format?
3. Can MSOLAP send data from one cube to another? Can multiple cubes submit data to a summary cube?
4. Can MSOLAP handle rule based allocations and adjustments?
5. Will MSOLAP scale to handle cubes with dimensions of the following sizes:

1. Account – 10,000 members

2. Entity/Cost Center – 16,000 members

3. Time – 17 members

I assume youre referring to the analytic architect? What is meant by MSOLAP, is that an OLAP viewer or do you mean Microsoft SQL Server 2005? I going to assume the latter.

a. As noted in the Crystal Reports post, this is actually just Lawson Portal forms that allow you set up the sources and destinations for all the dimensions and measures. So I guess they are using their server side code to do the actual ETL from the transactional tables.
b. Not sure what you mean by relational format, typically the data you stored in a cube is coming from a relational format.
c. the word "submit" is a bit confusing here. Id be curious to know what the purpose of having one cube be based off of multiple cubes would be since all the data would theoretically be coming from the same source. But, in SSAS 2005 (and soon 2008) you have Cube Perspectives which allow you to create smaller cubes based off a master cube.
d. yes, there are several different ways of handling this
e. its difficult to say just based on that but Im working with a cube right now that has 8,000 Account members so my gut reaction would be yes.
