Well there's apples to oranges, and then there's apples to fiberglass. This one lands in the fiberglass class.
I'm not sure of what integration you want to do, but if it has anything to do with shared data, both from and to the DB's... you can't get more incompatable. MS uses MS-SQL, which uses (among other things) stored procedures, triggers, etc. Mambo, using mySql, has none of those and they can't be "hooked" without a massive middle layer to translate/convert/pass to both sides.
Even if you only want to do readonly data from the MS side, you'll still need to code something for data connections. AFAIK, Mambo has no plans to use adodb until (maybe) v.5
Anything can be done, but the question is... how big is your bank account?
