Heh. That's pretty much exactly what the LINQ stuff in the .NET packages 
does. An XML file looks like a SQL server at the source code - you just 
build a different db connection object at the beginning.

If you're going to be filtering your own values anyway, look into the 
non-SQL databases like metakit. The primary advantage of the SQL databases 
is you can write expressions in SQL that manipulate an entire table (like 
finding the max, min, average and sum of a whole column) in one statement. 
If you're going to do that yourself anyway, it's probably easier to have the 
code linked into your app than it is to try to install postgress but only if 
it's already not installed *or* if you have permission to use it, etc. :-)
